It seem like all PRs fail in the build step Update Preview link comment below Netlify Preview (PR only). The error is
Error: The template is not valid. .github/workflows/build-process.yml (Line: 124, Col: 20): Error reading JToken from JsonReader. Path '', line 0, position 0.
From the error message it seems like the netlify step did not produce any output, so that steps.netlify.outputs.NETLIFY_OUTPUT is the empty string.
E.g. in
