@gitcodernitish I wonder if you enabled alpha features in your deployment?

[nitish-rbrk]

Got this working , Enabling alpha features was the miss. Thanks @afrittoli .
Can we add this in the documentation ? I think there can be more user like me who might hit this error.

I had the same error using the pipelines-in-pipelines feature. The referenced Tekton docs on Customizing the Pipelines Controller behavior don't really describe how to actually change the feature flag - they just state, that one needs to change a line in the Tekton Pipelines yaml file. If you're asking how to do this "on-the-fly" with kubectl apply I wrote a Q&A on stackoverflow. TLDR; installing the officially released Tekton pipelines yaml and enabling alpha features on-the-fly is possible using a piped combination of curl and sed:

curl https://storage.googleapis.com/tekton-releases/pipeline/latest/release.yaml | sed "s#stable#alpha#g" | kubectl apply -f -
