Could anyone explain how to fix? I’m not sure how to proceed.

Hi, @jiekechoo. 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 that the embedding model works fine with the OpenAI-compatible API on your self-hosted Dify 1.7.0 (plugin 0.0.19).
  • Despite this, the Dify UI shows a "Credentials validation failed: invalid response" error.
  • You provided curl commands and responses to demonstrate the issue.
  • Another user, issac2e, confirmed experiencing the same problem.
  • The issue remains unresolved with no updates or solutions provided so far.

What's Next:

  • 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!
