The check has failed https://github.com/actions/setup-go/actions/runs/5821942042/job/15811878197?pr=410 because the PR should wait till the 1.21 has been deployed to the runners.

I checked the default go is not 21 yet

[chenrui333]

rebased to the latest main and rerun the build

sorry about the hassle, I just recommit the change, which is better for review now :) (not sure how I messed up with the master branch merge commit 😮‍💨 )

[chenrui333]

Thanks for the patience :)

Encountered below issue when running Azure DevOps pipeline. Version 1.19 is the current working at my end.

[error]Failed to download version 1.21. Please verify that the version is valid and resolve any other issues. Error: Unexpected HTTP response: 404

I think, it downloads from this link https://storage.googleapis.com/golang/go1.21.windows-amd64.zip which is empty.

Could somebody help me on this.

Thanks in advance.

@Jayzon2019 you should use 1.21.0 or 1.21.1 rather than 1.21, which would resolve your issue

[Jayzon2019]

@chenrui333 . A thousand thanks to you.

I tried 1.21.1 and it was successful. I appreciate the immediate assistance.
