            On inspection, it seems that the `XCLIM_TESTDATA_BRANCH` environment variable is set to a tag that is not the latest in the `Ouranosinc/xclim-testdata` repository.

            This value must match the most recent tag (`${{ env.XCLIM_TESTDATA_TAG }}`) in order to merge this Pull Request.

            If this PR depends on changes in a new testing dataset branch, be sure to tag a new version of `Ouranosinc/xclim-testdata` once your changes have been merged to its `main` branch.
