Cannot read property 'description' of undefined

@duuz Could you post a response from the query inspector?

[alexanderzobnin]

This error caused by missing trigger with objectid obtained from the problem.get. That's strange, I'm trying to imagine a situation where it can happen. Plugin fetches problems, then get trigger ids from the response, and get triggers with that ids. And if trigger is not exist, this error happens. But what's a reason?

[alexanderzobnin]

@duuz that's a wrong response (for trend.get).

Query mode: Problems
Show: 'History' is worked only resolved
Show: 'Problems' or 'Recents Problems' returns 'Cannot read property 'description' of undefined'

[alexanderzobnin]

Ok, I've managed to reproduce this. Bug happens when you have a problem linked to the not monitored trigger (with disabled item, for instance).

Fixed in 13b0a2db787d763c53ace8876d7aca7ee9bae5bc

[JSylvia007]

I can confirm that the update fixed my issue.

Grafana v7.0.0 (aee1438ff2)
Zabbix Plugin Version 3.12.1
Zabbix Server 4.4.8
Ubunti 18.04.4

[forum77alive]

My issue (cannot read property 'description' of undefined) fixed too, but now i get "Cannot read property 'length' of undefined" on one of the zabbix-servers

[sirovstrukelj]

I've updated from 3.12.0 and the issue persisted until I cleared all the cookies related in my browser to the domain where Grafana was running.
