Expected behavior
Based on my understanding of the go code, I think it is because the plugin has not been started yet (maybe the plugin is abnormal), but dify-api has requested the plugin service to execute the plugin.

I don't know if what I think is right. I don't know where the problem is now. I hope to get a reply.

[NieRonghua]

Please close this issue. This panic does not cause a service-level error. I have resolved the issue.

[kingfs]

my local dify is use dify 1.8.1 and plugin daemon 0.3.1, also found this panic

[QuantumGhost]

I have encountered this issue too while trying to resolve this issue.

I make a tiny adjustment to the source code of plugin daemon to get a more comprehensive traceback.

The following traceback are from my debugging docker image. The log s: <nil> indicates that the receiver s of method setupStdioEventListener is nil. The traceback also confirms this. The first element in parameter list is 0x0, as the follow line shows:

plugin_daemon-1  | github.com/langgenius/dify-plugin-daemon/internal/core/plugin_manager/local_runtime.(*stdioHolder).setupStdioEventListener(0x0, {0x40007dc2a0, 0x24}, 0x400145ad30)

I suspect this is a timing issue in connection setup and listening.
