We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for all the commit author(s) or Co-authors. If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google.
In order to pass this check, please resolve this problem and have the pull request author add another comment and the bot will run again. If the bot doesn't comment, it means it doesn't think anything has changed.

The gRPC project recently released 1.19.0 - why not go all the way? Could you try updating to 1.19.0 and see if we get any errors?

Could you try updating to 1.19.0 and see if we get any errors?

Yes, I'll do it

[klim0v]

It's work

Nice, thanks! I'll just need to confirm with @achew22 that this is still correct in Bazel land before merging.

grpc is a dependency that gets managed by rules_go so this is good to go. Thanks so much for the PR!
