Google Sheets OAuth fails with 400 Bad Request in GlideOS

Hello everyone,

I am using GlideOS on the Free plan and trying to connect Google Sheets to my project, Vereda BPO.

When I click Connect and select my Google Workspace account, Google displays this error:

“400. That’s an error. The server cannot process the request because it is malformed.”

The Google Sheets integration remains disconnected. I have not granted the requested permissions or changed any project settings.

The error page does not show a more specific code, such as redirect_uri_mismatch. GlideOS also could not access the technical OAuth logs to identify the cause.

Has anyone experienced this issue with GlideOS and the managed Composio OAuth flow? Is there a known fix or a way to diagnose the authorization request or redirect URI without repeatedly retrying the connection?

I would appreciate any guidance. Thank you!
