Dify version

1.4.2

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

Hello,

I just updated form 1.4.0 to version 1.4.2.
And the two plugins, azure_openai and azure_ai_studio, no longer work.
However, the openai and ollama plugins work fine.

azure_openai plugin version: 0.0.16
azure_ai_studio plugin version: 0.0.3

To reproduce, just use a model from a chatbot

✔️ Expected Behavior

have no error

❌ Actual Behavior

For azure_openai, I get the following error:

[azure_openai] Error: PluginInvokeError: {"args":{"description":"[models] Error: [Errno 2] No such file or directory"},"error_type":"InvokeError","message":"[models] Error: [Errno 2] No such file or directory"}

in log api container :

@dosubot[bot] commented on GitHub (Jun 12, 2025):

For the "No such file or directory" error with the azure_openai plugin, this is often caused by a missing file in the Docker environment—commonly a PM2 PID file or a plugin artifact. The recommended fix is to stop and remove all existing Docker containers and images, then pull and start fresh containers. This has resolved similar issues for others after upgrades or migrations [source].

For the azure_ai_studio plugin's TLS CA certificate error, the message indicates that the file /usr/local/share/ca-certificates/dify.crt is missing inside the container. This usually means the certificate was not mounted or created as expected. Double-check your Docker volumes and ensure that the certificate exists at that path inside the relevant container. If you don't require a custom CA, you may need to update your plugin or environment configuration to not reference this file.

No breaking changes between 1.4.0 and 1.4.2 were found that directly affect these plugins' file paths or TLS handling. If you migrated or changed your Docker setup, re-check your plugin installations and any custom file mounts. If you removed plugins before the upgrade, reinstalling them after the upgrade has also resolved similar issues for others [source].

This seems to be a connection issue between dify and azure

For the azure_ai_studio plugin, the error is staying the same
