Should be ready to merge after you sign with CLA.

Should be ready to merge after you sign with CLA.

Hello @beniamin I am not seeing any prompt to do the signing as was the case in my first PR, would signing this using git commit -S -m work?

[beniamin]

I think all you need to do is to force a new commit, I saw that in your previous PR the CLA check has passed. Maybe now it's just stucked in "waiting for stauts to be reported."
