Hi @EItanya – could you please review this and let me know if any additional licenses need to be added or removed?

Will look today!

I think for now let's:

1. remove python license linting and separate into a different later PR if we decide we need it. I don't know about the correct way to do that yet
2. Update the SHA of the istio tool to be a valid release and test again

I’ve refactored a few things and updated the SHA for the Istio tool to 1.26.1. Could we possibly re-trigger the actions?

Hi @EItanya - GitHub CI failed because v1.26.1 isn’t available for istio/tools/cmd/license-lint. Should we switch to @latest or a commit SHA? Thanks!

Ah, can you look into why this is failing, @EItanya?

[abhinav-1305]

Hi @EItanya - probably lets get this merged in after fixing the CI?
