NullReferenceException when creating a release from GitHub action

Hello,

I’m in the process of migrating to using GitHub actions to create releases in Octopus and I’ve run into an issue where Octopus Server throws a NullReference exception when I try to do so, and I can’t work out why. I have upgraded my server to latest version (Version 2022.4 (Build 8394))

My GitHub action looks like this:

    - name: Deploy release in Octopus Deploy 🐙
      uses: OctopusDeploy/deploy-release-action@v3
      env:
        OCTOPUS_URL: ${{ secrets.OCTOPUSSERVERURL }}
        OCTOPUS_API_KEY: ${{ secrets.OCTOPUSSERVERAPIKEY }}
        OCTOPUS_SPACE: ${{ secrets.OCTOPUSSERVER_SPACE }}
      with:
        project: 'MyProjectName'
        release_number: '${{env.package_version}}'
        environments: |
          dev

The log on GitHub seems to be resolving all the env variables fine, and the API key works fine for pushing the packages

And the log on the server looks like the following. Any ideas what’s not getting set correctly?

Hi @Iain_Brown,

Thanks for getting in touch! I’m sorry to see you’re hitting this roadblock. Unfortunately I can’t tell conclusively what’s causing this error to be thrown at this stage, but I have a few questions to hopefully narrow down what might be going on.

Is this a tenant-required project? If so, you can use the deploy-release-tenanted-action to pass in tenants/tenant tags into the command.

Does this project have required prompted variables? The values to these variables need to be supplied when creating the deployment via:

      variables: |
        Foo: Bar
        Fizz: Buzz

Is this a version controlled project?

Lastly, would you be willing to send a copy of the build log for us to look into? If this proves to be needed, you can upload it to this secure link. :slight_smile:

I hope this helps for the time being. I look forward to getting to the bottom of this one!

Best regards,

Kenny

Hey Kenneth,

Thanks for looking into this. I managed to work it out in the end, I was using the wrong action, I should have been using the Create Release action, not the Deploy Release action. So it was an error at my end, but it’d be nice if the server returned a better error if this happens, it’s fairly easy to get terms confused.

Cheers

Iain
