Full error below, but we get a variety of errors showing different columns that is 'cannot include'. This is just started to happen recently.

I am creating an app for users online shops where they can connect facebook integration for their shop by providing Pixel id, app id, app secret, access token. From our side we get page access token from it and save all the data in our db and then use it to send events. Everything worked fine for about 1 week but at 1 day 4 stores have a problem "Error validating access token: The user has not authorized application xxx" when trying to send event. I will appreciate your help in this problem.

Dear Developer Community,
I am currently facing a challenge with the Facebook API, specifically the GET /{live-video-id}/live_comments feature. My aim is to fetch live comments from a specific Facebook Live video. I have been following the official documentation and using the example code provided:
var source = new EventSource("https://streaming-graph.facebook.com/{live-video-id}/live_comments?access_token={access-token}"); source.onmessage = function(event) { // Code to handle event.message };
Please refer to my pictures for error conditions
However, every time I run this script, I encounter an Error 503 response. Despite trying various troubleshooting steps, the issue persists, which leads me to suspect a possible problem with the API itself.
I am reaching out to ask if anyone in the community has faced a similar issue and how you managed to resolve it. Any advice or shared experiences would be greatly appreciated.
Thank you all for your time and assistance.
Best regards,
Hank
