Description of problem:

We have updated ARO from 4.8 to 4.9 and noticed there is issue with pipelines(see the below error), which is Pipeline is not getting triggered after Pull request is created in Azure Devops.

admission webhook "webhook.triggers.tekton.dev" denied the request: mutation failed: cannot decode incoming new object: json

So when i checked, i see that it is bug in 1.1.2v and it was fixed in 1.5.2v release.
So, i have updated to the latest version of pipelines operator which is 1.7v

But even after updated the issue is not resolved.



Version-Release number of selected component (if applicable):1.7v


How reproducible: Upgrade to 1.7v of pipelines operator


Steps to Reproduce:
1.Create pull request in Azure Devops
2.Check the pipeline pod logs
3.check the pipelinerun of that pipeline, which will show that new pipelinerun didnt happen.

Actual results: Pipeline didnt get triggered after the PR is created in ADO


Expected results: Pipeline should be triggered as soon as the PR is created in ADO



Additional info: We are blocked with deployments because of this issue.

I suspect this also have link with the API's deprecation in 1.22v of K8S which is used in ARO v4.9.
