I am working on a React app that's running on AWS Amplify. My React app is using the react-router-dom library to route to different components. After running amplify publish in the CLI, at the root of the app (obktraining.com) everything is fine in the browser, I can also route to other components in the app just fine as well. But when I refresh my browser while I am on a route (obktraining.com/menu), I get an Access Denied error message.
I have found other posts about similar issues regarding rewrites and redirects in Amplify, but the solutions given do not work for me.
Here is an image of the error:
My Amplify app rewrites & redirects :
Again, the error only displays when I refresh on a route (obktraining.com/menu or obktraining.com/drinks) not on obktraining.com. Is the issue being caused by the react-router-dom library or is it an issue with Amplify settings? I am not sure where to go from here.
I have been facing the same error since days.The error is being caused by the amplify settings. The solution is simple,
Edit your Rewrites and redirects by adding a new rule.
source address = </^[^.]+$|.(?!(css|gif|ico|jpg|js|png|txt|svg|woff|ttf|map|json)$)([^.]+$)/>
target address = /index.html
status = 200 (Rewrite)
Country code can be left blank
Save and try refreshing your app again. It should probably work.
use this for reference: https://docs.aws.amazon.com/amplify/latest/userguide/redirects.html#redirects-for-single-page-web-apps-spa
Then you can just put in (as Dhruv Godambe posted above)
</^((?!.(css|gif|ico|jpg|js|png|txt|svg|woff|ttf)$).)*$/>
as the Source address and
/index.html as your target address
You can navigate to 'rewrites and redirects' in your app from AWS Amplify console and click on edit and select open text editor, and add this piece of code in your array(if present) else put the array braces around it.
{
"source": "</^[^.]+$|\\.(?!(css|gif|ico|jpg|js|png|txt|svg|woff|ttf)$)([^.]+$)/>",
"target": "/index.html",
"status": "200",
"condition": null
}

I have faced the same problem.
I was using Manual Zip File (Compressed) download (wrong).
Here is how to deploy manually correctely:
Run this command
npm run build
Now a build folder will be created.
2. Compress the content of this folder
Not the content of the whole project.
You chnage directory to the build folder and Compress the content in side.
3. Upload that compressed file Inside the build directory
Now this should work just fine.
:)
The correct rule should be like this:
Source address: </^[^.]+$|\.(?!(css|gif|ico|jpg|js|png|txt|svg|woff|ttf)$)([^.]+$)/>
Target address: /index.html
Status: 200
I was getting the an Access Denied error message too. The error went away when I followed the documentation described in the answer above, but then I got the white screen problem described above too.
Reviewing the steps I noticed the auto-complete for the "Destination Address" listed in the "Rewrites and redirects" settings was /. When I tried using / as the "Destination Address" instead of /index.html I no longer got the white screen and got the expected page content.
Sharing what I found in case this helps others who are seeing a white screen after fixing the error with the rewrite rule described in the answers above. (Note as of Nov 2022 the "Rewrites and redirects" setting page uses the wording "Target Address" instead of "Destination Address".)
I have faced the same problem. I was zipping build folder, but not the contents within the zip folder.
Here is how I fixed it:
Run build command
npm run build
Now a build folder will be created inside your project directory.
Open build folder.
Compress the contents of build folder, and not build folder.
Now upload this new zip created from sub files and folders from build folder.
App will run fine on AWS Amplify.
I got the same error,
I zipped the build folder first then uploaded it and got that error,
but when I just uploaded the folder without zipping it, it worked fine !! weird!!
in my application I used the port 8080
I have successfully uploaded react app`s to github pages before, but this time when I try to upload a new page the code is pushed and everything looks fine in the repository, everything loads fine in the localhost. The problem is when I access the website in the console i get the error message above.
const res = await axios.get(' https://api.open5e.com/monsters/?limit=1086');
I am using this API, the limit is above 50 but I don`t believe this is the reason for the crash but I cannot think of anything else.
Website 1: (Currently redirects you to a 404 error page, as part of my attempt to solve the problem)
https://ottotsuma.github.io/MonsterSearch/
Repo - Website 1:
https://github.com/ottotsuma/MonsterSearch
Website 2:
https://ottotsuma.github.io/MonsterApiReact/
Repo all code:
https://github.com/ottotsuma/DnD-React
I also get this error in localhost and the hosted website: Uncaught TypeError: Cannot use 'in' operator to search for 'default' in undefined. But since the website was working as intended so far I have just ignored it.
I was hoping if anyone else has had a similar problem with gh-pages they might know what I have done wrong.
Kind regards,

I am in the process of deploying a dynamic, React.js app to Heroku and wanted to test it out by using 'heroku local' to see if it works before pushing it to Heroku. Everything seemed to be working fine with the server - my database console.log message logs to the terminal signifying everything is going well - but when I try to access the website which is on localhost:5000, I get an error message of 'Cannot GET /' and the console prints a message saying , 'Failed to load resource: the server responded with a status of 404 (Not Found)'. My React.js files are all within the build folder which in conjunction with all of the other files, were pushed to git and commited, but for some reason my files are not showing up. I would greatly appreciate if someone could help me determine what went wrong. Sorry if my question is a little vague; please let me know if I can clarify something in better detail as I am fairly new to programming.
I've added a proxy to one of my package.json files to help with url routing; possibly this could be causing the issue?
Also, if it helps at all, a photo of my folders within Visual Studio code are listed below:
my react app is working locally but after the deploy, I faced the problem when I press any button there is no problem but if I want to refresh I see that problem "404 - File or directory not found."
I found this solution:
https://github.com/ReactTraining/react-router/blob/v3/docs/guides/Histories.md#browserhistory
Configure Your Server
"Your server must be ready to handle real URLs. When the app first loads at / it will probably work, but as the user navigates around and then hits refresh at /accounts/23 your web server will get a request to /accounts/23. You will need it to handle that URL and include your JavaScript application in the response."
But I don't know how can I do this
I try something but it doesn't work
TRY
npm run build, this will create build folder inside your project root folder
if you want to deploy to remote server just transfer that build
folder.
npx serve -s build on windows, if you are using mac kindly see if it is still npx.
then try to refresh every path of it
hope this works, happy coding.
Since the server cannot find the static content in the directory (i.e. not found the file /tomcat/accounts/23), it will give you 404 unless you have additional route handling.
In React routing I think you can try with HashRouter

HashRouter vs BrowserRouter
just started working with reactjs recently, month or two..not a pro but can find my way around.. I am using create ract app (quickie ,that ships with service-worker) and my setup is such that I am deploying react app in the root of my java REST application, so all my service rest calls are in relative format, e.g /rest/myservice/123 etc.. and they work just fine..
but recently I started getting strange errors, and rest calls stopped working..
if I execute RET URL from browser .... nothing happens index loads... when I test with postman REST works just fine it also works in safari or if url is localhost... ...so after hours of frustration i discovered that service worker doing its .... caching . my rest calls are getting intercepted and they never make it to server... and there is nowhere that it mentions about how to overcome it, neither in service worker docs nor in create-react-app docs ...nothing is mentioned about this use case...... this is so pathetic...
I figured it out after numerous trail and errors... but it did not stop there..
I went ahead and deleted the service-worker registration entry from index.js also deleted service-worker file and rebuild the app. well service-worker.js file is still there... it showed up in build folder after I rebuild the project..... what is it with create-react-app did they got paid by google to include service-worker? or what is going on? why can not I remove it? and how do I prevent it from canceling my rest url calls?
when I type : https://xxxx.io/x/referal/refCode/3429878 it just loads application...
what else am I missing?
got the answer over #Redit needed to unregister worker...
