How to use Screen Lock Orientation API for Angular App in Modern Browsers

I have an angular app that I would like to force users to view in "portrait" mode even when rotated in mobile browsers. I'm attempting to use the screen.orientation API, but I'm getting the error:
"Uncaught (in promise) DOMException: screen.orientation.lock() is not available on this device."
The short version of code that I've used in trying to debug in the console is:
screen.orientation.lock("portrait")
This returns the error provided above. I have tried this on both MS Edge version 107.0 and modern versions of chrome, on different machines and devices and all yield the same result. In looking through other articles all are old posts and point to use this API, which seems as if this is no longer supported by modern browsers.
Is there another way to do this, or would I need to use CSS to render the page differently when detecting a change state of the orientation?

download and online stream is not working in parallel

We have encountered a problem, where we are downloading the video on my application home page and playing it in the videoPlayer page. Playing the video is getting stuck since download is in progress and the streaming request to google-cloud-bucket is in "pending" status(refer the screenshot).
As soon as download completes, video starts playing on videoPlayer page.
Can someone suggest any idea/solution for this usecase. There is an error message which is coming on console(on production) and on UI on local dev env.
Error Message: Uncaught (in promise) DOMException: The play() request was interrupted by a call to pause().

How can I troubleshoot a "Please Connect Camera" browser message from appearing after an image is captured?

I'm working on a React site with an image capture page and after the image is captured, the Chrome browser shows an error:
passportprint.com says
Please connect the camera.
The issue is intermittent. Has anyone seen this? How would I troubleshoot this error?
I'm using Gatsby JS for the framework.

CEFSHARP Video player don't work on weibo.com site

I can not see the videos on the weibo.com website.
Debugging sees this error:
Uncaught (in promise) DOMException: play() failed because the user didn't interact with the document first.
For example watch this link:

Uncaught (in promise) DOMException: play() failed because the user didn't interact with the document first.
This means that some script tried to call the play method of a video object, but this was prevented by the browser, because this call was not directly related to a user interaction, that clearly indicates that the user wants the video to play at this point.
This is done to thwart attempts to autoplay videos without the user actually wanting this to happen - which can in the least be annoying, and at worst even costly (for example on a metered/mobile connection.)
But if this is not a problem you are experiencing with any code you have written yourself, then you can only ask the people behind this website to look into that for you - you’ll have to check what contact options or bug report possibilities they provide.
