Dify version

1.1.2

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

Image
I used the custom self-deployed docker mode. When I upgraded to 1.1.2, I encountered this problem when uploading md format documents and using parent-child segment preview.
When I switched to the dify file extraction solution, there was no such problem

I found a similar unsolved discussion titled Node Code run failed, which was last updated on September 3, 2024 [1].

Regarding the "[Errno 111] Connection refused" error in a Docker-based self-hosted environment, this issue can often be caused by missing or incorrect configuration settings. In the context of Dify, this error might occur due to a missing CELERY_BROKER_URL environment variable. Ensure that this variable is properly configured in your Docker environment to specify the correct RabbitMQ connection string [2].

Additionally, when dealing with OpenAI-API-compatible models in a self-hosted Dify Docker setup, replace '127.0.0.1' with 'host.docker.internal' in your configuration. The full URL should be 'http://host.docker.internal:10000/v1/chat/completions'. If system proxy environment variables are set, you may need to unset them using:

unset HTTP_PROXY
unset HTTPS_PROXY

[3].

After upgrading to Dify 0.14.0, ensure that SANDBOX_ENABLE_NETWORK is set to true and configure the required sandbox environment variables. Verify that the sandbox service is properly connected to the Docker network and that both the web interface and sandbox service are on the same Docker network [4].

If you encounter a Server Unavailable Error after upgrading, replace 'localhost' or '127.0.0.1' with 'host.docker.internal' in your Dify configuration for the service [5].

I found a similar unsolved discussion titled Node Code run failed, which was last updated on September 3, 2024 [1].

Regarding the "[Errno 111] Connection refused" error in a Docker-based self-hosted environment, this issue can often be caused by missing or incorrect configuration settings. In the context of Dify, this error might occur due to a missing CELERY_BROKER_URL environment variable. Ensure that this variable is properly configured in your Docker environment to specify the correct RabbitMQ connection string [2].

Additionally, when dealing with OpenAI-API-compatible models in a self-hosted Dify Docker setup, replace '127.0.0.1' with 'host.docker.internal' in your configuration. The full URL should be 'http://host.docker.internal:10000/v1/chat/completions'. If system proxy environment variables are set, you may need to unset them using:

unset HTTP_PROXY
unset HTTPS_PROXY
[3].

After upgrading to Dify 0.14.0, ensure that SANDBOX_ENABLE_NETWORK is set to true and configure the required sandbox environment variables. Verify that the sandbox service is properly connected to the Docker network and that both the web interface and sandbox service are on the same Docker network [4].

If you encounter a Server Unavailable Error after upgrading, replace 'localhost' or '127.0.0.1' with 'host.docker.internal' in your Dify configuration for the service [5].

This problem is different from the one I encountered. The formats I mainly use are doc and md. When using the doc format, this error does not appear, but this error will be reported when using the md format. I think this has nothing to do with redis?
