Blank App in Teams

[bderry71]

We've got a issue where the app loaded once and was able to see it once. Then realized it took over the Chat Channel of where ever I put the Tab. So I deleted it and made a new channel then added the tab back. Then it came up blank. Then I deleted the whole team and rebuilt it. Added the second Channel then added it back to a tab. It still came up blank.

How do I get the logs you want?

@bderry71 , Thank you for sharing the logs with us. Can you please confirm if you are able to access SharePoint site and root site collection.

[bderry71]

Yes, I can get to the Site as I built it.

@bderry71, Please allow us some time to analyse this and we will get back to you ASAP.

@bderry71, We will need few clarification related to permission to understand the issue, From the logs its clear that you have shared it looks like you don't have permission as its giving 403 error. Can you please try to access below URL in graph explorer and confirm if that is working for you? https://graph.microsoft.com/v1.0/sites/csusanbernardino.sharepoint.com:/sites/CSUSBTeamsEOCSite?$select=id

Also confirm if ''Sites.Manage.All' permission is added while configuring permissions for TEOC App.

OK. I clicked the link and this is what I got back.

`

I was never prompted for login with that link.

I also tried it with a Outlook.office365.com/mail session and it gave the same error:

{"error":{"code":"InvalidAuthenticationToken","message":"Access token is empty.","innerError":{"date":"2023-10-19T17:04:35","request-id":"ae5b16aa-2d2e-4f00-a750-d640f451dc16","client-request-id":"ae5b16aa-2d2e-4f00-a750-d640f451dc16"}}}

@bderry71, Did you try that with Graph API? Can you please share screenshot of all the permissions you have configured for the App and if admin consent is granted for that?

[bderry71]

Here is the current permissions setup.

@bderry71, Please allow us some time to analyse this issue. Meanwhile can you please try to add TEOC app in some other channel or open that as an app in teams instead of adding that in channel and let us know if its working?

[v-asshrirao]

@bderry71,Thank you for your patience. Can you please confirm if you are the only one who is facing the issue and can you please also confirm if you have tried adding TEOC app directly instead of adding that in channel?

We followed the deployment guide and performed all the steps, We are also facing the same issue when we add launch the app in Teams we are getting blank dashboard except Welcome message.

We also tried adding the app via channel and directly app also. in both the scenarios we are getting the blank screen.

Please find the attached Logfile, Blank app screenshot, Azure App Permissions TeamsEOC_Log.log

It would be great we can have update on the issue as we have tried all the possible options.
