An unhandled error occurred while serving the request

[VyacheslavPritykin]

When I click on signals, I occasionally receive the banner "An unhandled error occurred while serving the request."
It does not affect the logs' output, so it's more like a visual noise.

Hi Vyacheslav, thanks for your message.

We think this is due to a bug in an earlier Seq version (perhaps a year or two old?) causing an invalid dashboard id to be recorded in your personal workspace.

The quick fix should be to go to your user avatar, click Workspaces, and then find and delete the Personal workspace.

You can re-create this through the same screen, and populate incrementally as you find and select signals in the signal bar.

If you're on a Seq instance without a large number of signals etc. present, then not having a Personal workspace is also fine - you'll see all available signals/dashboards etc. on every screen.

Hope this helps,
Nick

This Seq instance was installed last month, using the version that was current at that time

[nblumhardt]

Thanks for the info, we'll take a closer look 👍

[VyacheslavPritykin]

More details:

GET /api/users/current

GET /api/workspaces/workspace-54

When I click on a signal:
PUT /api/workspaces/workspace-54?version=1

I'm also getting this same error. Using Entra auth for Seq. This occurs when we make different signal selections and the dashboard tries to auto-save your preferences.

Seq Version: 2024.3.12680

[xantari]

Update: Deleting the personal workspace and recreating it does fix the issue as a work around.

@nblumhardt, should I keep my workspace intact for now if you need more information?

[nblumhardt]

Deleting the workspace now is fine, we should have enough information here to work with - thanks very much for all of the investigation 👍
