Thanks @nils-van-zuijlen for this PR - would you mind trying signing the CLA not via corporate contributor but via individual contributor? In that way you might not need to opt for the way to have a google account.

Hi @JeromeJu I reopened this in #3274, since Nils put the changes into the public domain. Can you PTAL there & close this PR if #3274 looks good? Thanks 😁

Thanks Nils for the change, I just bumped into this.
