error pathspec sdk-release-310 did not match any files known to git

This error message typically means that the branch or tag 'sdk-release-3.1.0' does not exist in the repository you are currently working with.

To verify if the branch or tag exists, you can run the command git branch -a or git tag -l respectively. If the branch or tag is not listed, it means that it does not exist in the repository.

If you are trying to checkout a remote branch or tag, you may need to fetch the latest changes from the remote repository first by running git fetch origin before checking it out.

If you are still having issues, double-check the spelling and capitalization of the branch or tag name as it is case-sensitive.
