There's no stack trace I could find. It comes up in the Metabase logs viewer, and it looks like it's catching the exception and logging it, rather than throwing a full stack trace. Here's the full log lines to give you an idea.

2026-10-01T12:36:02-07:00 INFO metabase.notification.send Done processing notification
2026-10-01T12:36:02-07:00 ERROR metabase.notification.send Error sending to channel channel/email: Error registering fonts: Metabase will not be able to send Pulses. This is a known issue with certain JVMs. See https://github.com/metabase/metabase/issues/7986 and for more details.

I'll look for a stack trace. I'm not sure there's more than what's written here. I did crosspost to the Metabase discourse and someone suggested edits to the dockerfile (although I don't actually know how Cloudron packaging works).

# Fix /tmp permissions and rebuild font cache (must be root)

Error message below is in the Metabase logs.

Metabase.notification.send Error sending to channel channel/email: Error registering fonts: Metabase will not be able to send Pulses. This is a known issue with certain JVMs. See https://github.com/metabase/metabase/issues/7986 and for more details

We are running the latest as of today - Metabase v0.63.19 (Cloudron 3.27.0).

Unclear to me if this needs to be fixed within Cloudron repackaging or if a bug was introduced on the Metabase side?

Any suggestions?

Apache Answer offers many official plugins, which are supposed to be used by building with the applicable plugins as detailed on this page:

Is there any way to enable more plugins in this Cloudron packaged version? We're specifically interested in the Google auth connector.
