Hi, @auxpd. I'm Dosu, and I'm helping the dify-official-plugins team manage their backlog and am marking this issue as stale.

Issue Summary

  • You reported a 404 error when using Anthropic models on a self-hosted Dify setup (v1.0.0, plugin 0.0.3-local).
  • The error occurs during token calculation in the model runtime, causing generation failures.
  • The traceback points to issues in the model manager and plugin model manager components.
  • No further updates or responses have been provided since the initial report.

Next Steps

  • Please let me know if this issue is still relevant with the latest version of the dify-official-plugins repository by commenting here.
  • If I don’t hear back within 5 days, I will automatically close this issue.

Thank you for your understanding and contribution!
