How do I resolve the “OAuth credentials are invalid or deleted” error for Google Chat backup?

If Google Chat backup stops with the error code BGOOGAP998, the OAuth Client ID/Client Secret configured in SysCloud is no longer valid (for example, the OAuth app was deleted in Google Cloud or the Client Secret was rotated). Generate new OAuth credentials in Google Cloud and update them in SysCloud Cloud Connections.

Step 1: Sign in to Google Cloud Console and select the project used for your OAuth app. 
 
 

Step 2: Go to APIs & Services -> Credentials.

Step 3: Select the Client ID you want to update

Step 4:  Click on +Add secret under Client secrets to create a new secret 

 

Step 5: Now copy the new Client Secret to update in the SysCloud Application

Step 6: Log in to SysCloud and go to Settings -> Cloud connection center. 
 

Step 7: Locate your Google Chat connection and click Edit (pencil icon) or open the connection details. 
 
  

Step 8: Click Refresh Credentials and paste the new Client ID and Client Secret, then click Authorize in Google Chat. 
 
  

Step 9: Return to the backup status page and confirm the backup resumes in the next backup cycle.
