@ashharrison90 did you have a minute to test it out too? |
|
yeah, worked perfectly for me and surfaced the error to the user. although i only tested the scenario you mentioned in the issue - i'm a little unsure what else to test in that area 😅 |
Thank you, that's more than enough! |

What this PR does / why we need it:
We're using the rxjs function
reduceinDashboardQueryRunnerandAnnotationsWorkerto keep re-renders to one. One challenge with usingreduceis that all observables involved need to be completed before any value is emitted. Having an unhandled exception in that chain will cause the reduce to never emit a value which explains #38985.This PR adds error handling for the call to datasourceSrv.get so we always emit values even if one of the data sources is missing.
Which issue(s) this PR fixes:
Fixes #38985
