TypeError: e is undefined #28120

Berbe · 2020-10-08T14:08:58Z

What happened:
TypeError errors pop up in console, sometimes making a Dashboard crash.

No error spawned by the server run with a debug log level: definitely seems like a frontend error bug.

What you expected to happen:
No error, no crash

How to reproduce it (as minimally and precisely as possible):
Fiddling with template variables in order to make a Dashboard refresh, sometimes not doing anything other than hovering over Panels.

Anything else we need to know?:
Other potentially related issues

Azure Log Analytics: TypeError: e is undefined #22199 Error looks very much alike
Dashboard variable dropdown crashes in play.grafana #24125 Video shows an error happening in a suspiciously similar way

@Berbe so the issues you have referenced is due to a different reason. I can see why you could think that they are related due to the error message but that is somewhat a standard error.

However the error you have posted has to do with the parsing of the URL. Could you share how the query string looks for your dashboard that crashes? That would help us resolve this.

Berbe · 2020-10-09T09:05:06Z

Thanks for this piece of information.
Maybe could it be an idea to make those error messages more specific, if that is possible? It would help both reporters & solvers.

For all the following errors, the URL was http://127.0.0.1:3000/d/<dashboard UID>/<dashboard name>?orgId=1&refresh=1m

Could you share a copy of your dashboard json? Just so I can see what template variables you have setup?

Berbe · 2020-10-09T16:44:36Z

I am a bit unsettled about giving out potentially sensitive data.
Hence, I anonymised the variables parts of the export JSON and will provide it to you through a share meant to expire within a day or so through a sharing mechanism available out there.

Here is that share (removed).
Please be mindful about that piece of information, use it for the purposes of this issue only & swiftly discard it as soon as not required anymore.

torkelo · 2020-10-11T11:27:37Z

You seem to have a data link that is causing this, need the panel json for the panel in order to replicate this

Berbe · 2020-10-12T10:09:43Z

Share (removed) (1d expiration)

I noticed some errors happened when I tried to update the template variables. In particular, I noticed requests to http://127.0.0.1:3000/api/datasources/proxy/1/api/v1/metadata ending up with HTTP 404. Is that expected?

mckn · 2020-10-13T15:05:14Z

@Berbe thanks for reporting this! I have opened a fix for this.

Berbe · 2020-10-16T00:38:39Z

Thanks a lot @torkelo, @mckn!
