I used claude-code-base-action to dynamically generate a website based on the content of a file, but I always encounter the Error: Bad substitution problem with a high probability.

GitHub Action Job：https://github.com/yeshan333/awesome-tech-weekly-zh/actions/runs/16385774613/job/46305071725

10 runs, at least 4 or 5 times will encounter this issue.
