Investigating
A recent change is causing 404 errors for clients who send messages to a URL which includes a trailing slash (/v1/projects/my-project/messages:send/ vs /v1/projects/my-project/messages:send). We are in the process of rolling back this change.
For clients that are impacted, removing the trailing slash from the send URL will immediately resolve the problem.
Resolved
The rollback is complete - service is fully restored.
