Plugin Daemon Internal Server Error : no available node, plugin not found

Discussion

I am running a tool/plugin in debug mode.
On https://cloud.dify.ai/plugins, it shows “Debugging Plugin”, and although I can select the tool and configure the node settings, I suddenly started getting the following error:

PluginDaemonInternalServerError: no available node, plugin not found

Stopping the debug run and restarting it does not resolve the issue.
Is there any way to fix this problem?

This usually happens when the plugin failed to install it’s dependencies.
If the package takes too long to install or too long to initialize itself, this could happen.

Thank you for your comment.

Referring to https://motherduck.com/blog/duckdb-versus-pandas-versus-polars/,
I found that the DuckDB library is implemented in C++ and its size is around 57–80 MB.
Since it is implemented in C++, there is a high possibility that it uses system calls that are not permitted.

Thank you for explaining PLUGIN_MAX_EXECUTION_TIMEOUT and PYTHON_ENV_INIT_TIMEOUT.
I learned a lot from your explanation.
