Your creating Google Credentials? If yes than make sure you’re adding correct scopes in Google Cloud.

I am a beginner. What scope are you talking about? I tried to add google sheet credential, enabled google sheet api.

I have made a video to create credentials for YouTube, Drive. You can take a look, process is the same, Instead of YouTube, you just have to enable excel sheet. When you reached the data access page:

  • Click Add Scopes
  • Search for Excel
  • Click the Checkbox
  • Click Save
  • Goto Clients Tab & create new credentials

still having same problem

According to error it says:
Problem generating the authorization URL missing ) after argument list

It says that there is issue with arg string you’re providing “missing )”, Please check the argument string you provided, is correct.

It looks like there’s a syntax error in your custom authorization URL—most likely due to a misplaced or missing parenthesis in the parameters. Double-check the OAuth2 settings in your credential configuration, especially the Authorization URL field. Make sure there are no typos, stray characters, or unescaped values in the query string. If possible, share the exact URL format you’re using, and I can help pinpoint the issue.
