i have a fairly complex data factory 18 pipelines, 120+ datasets 26 Dataflows. it has been working fine until last week when i tried adding a new dataset.
You can see that i am adding the dataset and spec the file path that it will point to in one operation.
it takes as much as 10seconds to execute this task
on publishing you get the following error
i discovered after a week of tearing my hair out and learning about ARM templates
that you can get around this bug by
Adding a new dataset but not spec the file path leave as the root
publish the dataset ... all fine
Edit the newly created dataset, spec the file path you want the dataset to point to
publish, all is fine
Observations the first does not take 10s, it returns instantly
