504 webhook errors in the Event Log without webhooks defined

daniel.lohse

I'm stumped about certain errors showing up in the Event Log regarding webhooks. We don't have a single webhook defined.

These are the error details:

Webhook [http://172.x.y.z:9011/internal/webhook] returned response code [504] when sending [JWTRefreshTokenRevoke] event with Id [<uuid>]

The Details modal doesn't provide any other information.

I see a couple of these a day and they're all classified as errors.

The list of webhooks in Settings > Webhooks is empty.

We're running version v1.47.1 in production but will update to the latest version shortly. I also see these in our staging environment and that has already been upgraded to v1.48.1.

Hmmm. I think this might be related to some internal webhooks FusionAuth uses to sync data between nodes. See for example https://github.com/FusionAuth/fusionauth-issues/issues/2257

Are you running multiple nodes or one node? Any other details you can share about your platform?

Yup, we're running multiple nodes. FusionAuth is deployed as a Deployment in Kubernetes. 3 pods per cluster and 6 clusters. These pods aren't accessible from the outside.

The issue you linked looks applicable.

Any other information I can provide?

Thanks @daniel-lohse.

This additional info would be helpful:

Type and version of your database
Any negative issues you see, unless this is only a worrisome event log entry
Any behavior you see that triggers these (if you have replication steps)

And I can file an issue.
