google-cloud-php: [Spanner] Running spanner emulator causes UNAUTHENTICATED error

When I try to connect to the Spanner emulator, I get the following error.

This only happens with grpc v1.36. Grpc v1.35 does not have this issue.

@taka-oyama we fixed by downgrading grpc to version 1.35.0

sudo pecl uninstall grpc
sudo pecl install grpc-1.35.0

Hi @taka-oyama I was able to verify that this has been fixed with google/cloud-spanner:1.49 (and grpc: 1.45)

I am closing this, but if you find if it is not fixed, feel free to reopen this issue 😃

@skuruppu I was able to confirm that it works with 1.37.1. Thank you! I will close the issue.

@skuruppu it seems to work well with version 1.37.1 thanks 👍🏽

@gsouf I’m so sorry. I didn’t type in the minor version number in my comment earlier 😦

Would you please be able to try installing grpc-1.37.1?

@taka-oyama unfortunately the latest Spanner release will not fix the problem. The underlying issue is in gRPC v1.36. @larkee filed an issue in the gRPC repo (https://github.com/grpc/grpc/issues/25810). I pinged the issue just now as well.
