Fatal error: No Queues driver configured

[ctreffs]

We encountered an issue trying to deploy the latest XCMetrics backend docker image via Google Could Run and are unable to resolve it.

Environment:

• PostgreSQL: v12
• docker image latest

Env variables are set to

• XCMETRICS_USE_ASYNC_LOG_PROCESSING="0"
• XCMETRICS_USE_CLOUDSQL_SOCKET="1"
• XCMETRICS_CLOUDSQL_CONNECTION_NAME="***"
• DB_NAME="database name"
• DB_USER="database user"
• DB_PASSWORD="***"

Google Could Run docker image start failed

{

}

Any idea what we could be doing wrong?

Good evening,

Hope you are doing well. It seems that we are also facing this issue and after a long debugging session we found out that this might be an error in the documentation, however we aren't really sure. I tried running the project locally to reproduce the error logs we are facing in the server, and this is what we found:

docker error (server error):

xcmetrics-xcmetrics-s-job-1  | 0xffffffffffffffff
xcmetrics-xcmetrics-s-job-1  | qemu: uncaught target signal 4 (Illegal instruction) - core dumped

and that's also reproducible on local machines, by using the following env variables, where the crash accures because of app.queues.use(...) not being set. And that's due to XCMETRICS_USE_ASYNC_LOG_PROCESSING being set to 0 which is required by the queues library.
