How does this help?

I'm not seeing a logic change

[RahulGautamSingh]

The issue is that Azure throws as error when we try to update targetBranch unnecessarily ie. trying to update it to same value.

New change:
Only add targetBranch to update-options if it is different from current one. This will prevent the error.

I expected this to require a change of logic in workers

I thought the same, and then coded it. After that I realised that the checks in the platform files is needed regardless of change in targetBranch so that we check targetBranch != undefined before passing value to the api call.

So I decidedto make changes to platform files instead of workers and plaftorm files.

Are you saying that targetBranch won't be passed to the platform if it's unchanged? Because that doesn't sound right to me - I thought your code passed it every time

[RahulGautamSingh]

Correct, workers change is needed. Feeling stupid now as that is that basic logic change that is must🤦‍♂️
