I'm getting an error using the

setup-nextflow

action in a few of my pipelines:

Input version '25.10.0' resolved to Nextflow undefined

It seems it just started failing today even though my gha workflow yaml hasn't changed. Perhaps this is a bug in nf-core/setup-nextflow with version resolution? yaml snippet:

- name: Install nextflow
        uses: nf-core/setup-nextflow@v3
        with:
          version: 25.10.0

error:

Input version '25.10.0' resolved to Nextflow undefined
Error: Cannot read properties of undefined (reading 'includes')
Error: Could not run 'nextflow help'. Error: Unable to locate executable file: nextflow. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also check the file mode to verify the file is executable.
Error: Process completed with exit code 1.

That seems to already be a reported bug (I happened to be looking at about the same time): github.com/nf-core/website/issues/4317 Hopefully a fix is in progress!

ah, I checked the issues in the setup-nextflow repo but not the website. Thanks Josh!

They also added a fix on the website end. Belt and suspenders!
