CFN - Task fails if there are no updates to apply about aws-toolkit-azure-devops

[stevejroberts]

Ok, we'll work at updating the tasks so that if the updatestack or execchangeset operations fails with a 'no changes' error, we'll output a warning to the task log rather than causing the task to fail. I don't have an ETA right now, but shouldn't be too long.

[stevejroberts]

The CreateOrUpdateStack task can perform the update using either a direct call to the service's UpdateStack API or by executing a change set. In both cases the task catches errors and inspects to see if it was due to a 'nothing to do' condition (which it has to do by inspecting the error message content). My guess is that in your case, the error messaging isn't getting trapped.

Can you post an example of the error message you are seeing when the update fails?

Hello,

this is the error from the build server

but this is the cfn stack error from the failed change set form the UI

Status:
FAILED - The submitted information didn't contain changes. Submit different information to create a change set.

Thanks. Are all of your stack updates being done using change sets?

[r2690698]

Yup, they are, the idea is that if we make any changes to a template or param on our cicd branch we test it, deploying and exacate the change set to QA -->PreProd then Prod as a unexecuted change set ready for change control to approve.

@steveataws brill thanks very much !

i have it just now to 'continue on error' so i get a 'partial success' in orrange. that option realy should not be enabled and the task sequence should still pass as 'success' in green other wise you will also be checking the logs to see if its a real error or a no changes error.

v1.0.8 has now been released which contains updates to the CloudFormation task to detect the no-changes condition and emit a warning, rather than failing the task.

Resolving issue; feel free to reopen if you still encounter issues.

@steveataws works perfectly HUGE thanks for a quick turn around !
