consistent failure with 500 server error

[ck3mp3r]

I've published a number of times in the last 2 weeks and now the api returns a 500 even though publish is successful.

Here is the output of the run in question:

I'm experiencing the same issue when trying to publish my flake for the first time.

Repository: https://github.com/sadjow/claude-code-nix
Failed run: https://github.com/sadjow/claude-code-nix/actions/runs/20838826311

The flake evaluates fine locally with nix flake metadata and nix flake show. The workflow sends the correct version and commit SHA, but the API returns 500.

Unlike the original issue, in my case the publish did NOT succeed - the flake doesn't appear on flakestry.dev at all.

This might also be related to flakestry/flakestry.dev#46 (ResponseValidationError).

Update: I did some debugging and found that annotated tags cause issues.

When using gh api repos/.../git/ref/tags/v2.1.2, it returns the tag object SHA, not the commit SHA. For annotated tags, this needs to be dereferenced to get the actual commit.

I updated my workflow to handle this:

- name: Resolve tag to commit SHA (for manual dispatch)
  run: |
    REF=$(gh api repos/${{ github.repository }}/git/ref/tags/${{ inputs.tag }})
    SHA=$(echo "$REF" | jq -r '.object.sha')
    TYPE=$(echo "$REF" | jq -r '.object.type')
    
    # Dereference if annotated tag
    if [ "$TYPE" = "tag" ]; then
      SHA=$(gh api repos/${{ github.repository }}/git/tags/$SHA --jq '.object.sha')
    fi
    
    echo "sha=$SHA" >> $GITHUB_OUTPUT

Now the correct commit SHA is being sent (cf18573... instead of the tag object 639896...), but I'm still getting 500 errors.

This might be a separate issue in the Flakestry backend, or perhaps the flakestry-publish action itself has a similar problem with annotated tags when running on tag push events?
