Question

Google SecOps + Google Chat: List Spaces works, but message actions return 404

+1

I am configuring Google SecOps with Google Chat for a playbook.

What works:

The target space is returned correctly, and the app is already added to the space.

What fails:

Both return this exact error:

Error executing action "GoogleChat - Send Advanced Message". Reason: An error occurred: b'<h1>Not Found</h1>\n<h2>Error 404</h2>\n'

I also confirmed that Space Name must be passed in the full resource format:

spaces/{space}

If I pass only the raw space ID, I get a malformed resource name error.

At this point, List Spaces works, but sending messages still fails with 404 even though:

Has anyone seen this before or successfully implemented this end to end?
