Hi, @Alex-lsky. 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 in Dify v1.7.1 with plugin v0.42 on a self-hosted Docker setup, the Bedrock plugin fails to invoke Qwen and deepseek models due to an unknown model prefix error.
  • The Claude model works fine, but the error log shows a PluginInvokeError citing an unknown model prefix "qwen."
  • Another user, taminaho, confirmed a similar issue with openai/gpt-oss-20b and openai/gpt-oss-120b models on Amazon Bedrock, encountering an unknown model prefix "openai" error.
  • This points to a broader problem with model prefix recognition in the Bedrock plugin.
  • The issue remains unresolved with no recent updates.

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 to keep the discussion open.
  • Otherwise, this issue will be automatically closed in 5 days.

Thank you for your understanding and contribution!
