What does it mean?
Error in event handler for (unknown):
TypeError: Cannot read property 'response' of undefined
at t.runtime.sendMessage.e (chrome-extension://mlomiejdfkolichcflejclcbmpeaniij/dist/content_script_bundle.js:1:22694)
Chrome extension with id mlomiejdfkolichcflejclcbmpeaniij seems to be ghostery. You probably should disable it for local development.

I am trying to deploy my portfolio website. It shows the proper log-in animation but then just shows a white screen. I have no idea why this is happening, the logged error message references unhelpful code from the site generator.
the error is in console. and in Skills.js file in line 48.
TypeError: Cannot read properties of undefined (reading 'map')
you can fixed it by adding question mark like this :
{ skillsSection.skills?.map((skills, i)=> ....
and there is another error : twitter.js:14 Uncaught TypeError: Cannot read properties of null (reading 'innerHTML')
in twitter.js file in line 14
just add question mark there too. like this :
if (!document.getElementById("twitter")?.innerHTML.includes("iframe"))
The following code does not produce a error but nothing happens. I'm using ng v11, reactive forms, and primeng 11. What am I missing?
<p-checkbox label="Confirm"
formControlName="chkConfirm">
</p-checkbox>
typescript:
this.chkConfirm?.setValue(true);
edit:
Adding error message found in console:

I am trying to use Selenium for Python eith the Chrome webdriver to automate the download of a file.
My program works perfectly up to the last step (clicking on the 'download' button) at which point a dialog box is triggered with the text:
"An error has occured in 'site url': Uncaught TypeError: Cannot read property 'getColomnSet' of undefined41"
What does this error mean and what are the most probable causes?
For reference, here are the last few commands of my program:
try:
elem = wait.until(EC.presence_of_element_located((By.ID,'element_1_id')))
finally:
elem1 = driver.find_element_by_id('element_1_id')
elem2 = driver.find_element_by_id('element_2_id')
action = ActionChains(driver).move_to_element(elem1).move_to_element(elem2)
action.perform()
elem2.click()
This error message...
An error has occured in 'site url': Uncaught TypeError: Cannot read property 'getColomnSet' of undefined
...implies that your program was unable to read the property getColomnSet while trying to download the desired file.
Possibly, the main problem is the js involved to download the document is invoked before the client renders the HTML DOM completely.
The relevant HTML, a bit more of your previous lines of code and the error stack trace would have given us some more idea about what's going wrong.
Solution
You can induce some measures to wait till the complete DOM Tree is rendered following the discussion:
Generic funtion to check if page has completely loaded in Selenium
A couple of facts:
In your code trials I don't see you interacting with the element (By.ID,'element_1_id') so possibly you can remove the step of presence_of_element_located() for the element (By.ID,'element_1_id').
If you still require presence_of_element_located((By.ID,'element_1_id')) catch the exception and initiate required steps.
As you invoke move_to_element() over elem1 and elem2 and moving ahead invoke perform() you need to induce WebDriverWait with expected_conditions as element_to_be_clickable(locator)

Uncaught Error remote.js
Try the following - it works on Salesforce Lightning UI screens:
WebElement element = driver.findElement(By.id("your ID"));
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", element);
I followed the Custom remote validators documentation
I have <script href="parsley.remote.js"></script> before <script href="parsley.js"></script> just before the end of html body and I'm seeing the following message on the console of Chrome Developer Tools:
Uncaught TypeError: Cannot read property 'on' of undefined(anonymous function) # parsley.remote.js:267(anonymous function) # parsley.remote.js:271
Part of paryley.remote.js code :
window.Parsley.on('form:submit', function () {
this._remoteCache = {};
});
On Firebug the error console message is
TypeError: window.Parsley is undefined
window.Parsley.on('form:submit', function () {
A small lab just a test html page with source dist js parsley
If I invert file reference parsley.remote.js and parsley.js, the error disappears, but according to the documentation, it's not the right way.
It's was bug, fixed in 2.1.3+.
Only include the remote version (assuming you need it).
I am working with a request object:
$this->request
and received the following error:
Undefined property: EventsController::$request
Are you certain you are running Cake 2.0 and not 1.3? What's the output of Configure::version()?
Cake only throws this error when the property is actually undefined. In 2.0 you should get a fully populated request object. Using $this->request in 1.3 throws the error you're receiving.
