Error Message

I deployed Dify on my cloud server, but encountered the following error when accessing the web installer to add a vendor model. I've tested both Dify versions 1.13.3 and 1.13.2, and the error occurs in both cases. My cloud server configuration is 2 vCPUs / 8GB RAM, the network is working properly, and I've retried multiple times with the same error. I hope someone can help me out.

❌ Actual Behavior

No response

extent analysis

TL;DR

The issue is likely due to network connectivity issues or caching problems when installing dependencies, and a workaround may involve checking network settings or adjusting dependency installation.

Guidance

  • Check the network connectivity of the cloud server to ensure it can access the required repositories for dependency installation.
  • Verify that the httpx package version 0.28.1 is available and can be downloaded from the specified URL or if it's cached locally.
  • Consider adjusting the dify-plugin version to one that depends on a different version of httpx if the specified version is not accessible.
  • Review the Docker configuration to ensure that network connectivity is properly enabled for the container.

Example

No specific code snippet is provided as the issue seems related to dependency installation and network connectivity rather than code syntax.

Notes

The issue might be specific to the network environment or the version of dependencies used. Ensuring that the server has proper network connectivity and that the required packages are accessible is crucial.

Recommendation

Apply workaround: Adjust network settings or dependency versions to resolve connectivity or caching issues, as the problem does not seem to be directly related to the Dify version itself.
