Ambiguous error message from Workflow extension when receiving error from Camunda

Workflows
1

When I use workflow-extension to start a process, which does not have process definition on Camunda yet, I received an ambiguous error in the console (see code below)

  • It only said “Data not found” which is really hard to detect the real problem
  • It comes from ContentStoreErrorHandler which I think it’s a missing from Workflow extension

Can you improve the message logs so administrator can understand the error easily?

Hi @son-fast-shard,

Thanks for the report! We are aware of this issue and want to improve logging in such error cases.

Also, we will evaluate changes in Data Services so that the ContentStoreErrorHandler doesn’t handle exceptions unrelated to content store.

Cheers,
Peter

Great. It would be great if you can send me a ticket that I can follow up.

Hi @son-fast-shard,

On Data Services side, see A12S-5507.
On Workflows side, see A12WF-1555.

Cheers,
