Deployment Pipelines - Dataset is different after a "Successful" Promotion from DEV to TEST

I've had a similar issue and after a bit of testing, I've found a workaround for my scenario. Posting here in case it helps others.

The change that broke it

My dataset is separate from my report.

Deployment pipelines were previously working without issue.

The only change I made was to rename the only security role in the dataset and deploy to dev.

Confirming the issue

To check that my assumption was correct, I changed the name of the security role back to what it was and redeployed to dev. Deployment pipelines worked again.

The workaround

I needed the security role renamed so to try and get dev and test to align, I deployed my PBIX with the renamed security role back to dev and then also manually deployed my PBIX directly to test. No need to delete first.

Pipelines now works again. 

Like I say, might not be suitable for all cases, but hopefully it is helpful to some.
