@IAMJOYBO Hello there! I'm here to help you with any bugs or questions you have while waiting for a human maintainer. Let me know how I can assist you!

To resolve the "PluginDaemonInternalServerError: no available node, plugin not found" error in Dify version 1.0.1 on a self-hosted Docker setup, you can try the following solutions:

1. Increase the Python environment initialization timeout by adding this line to your docker-compose.yaml:

   PYTHON_ENV_INIT_TIMEOUT: 320

2. If the above doesn't work, perform these steps:

   • Uninstall and then reinstall the plugin to address any synchronization issues.
   • Clear plugin data from the database by executing these SQL commands in the dify_plugin database:

     delete from plugin_installations where plugin_unique_identifier is not null;
     delete from plugin_declarations where plugin_unique_identifier is not null;
     delete from ai_model_installations where plugin_unique_identifier is not null;
     delete from plugins where plugin_unique_identifier is not null;

   • Clear plugin directories from:
     • /app/storage/cwd/plugins/plugin
     • /app/storage/cwd/plugins/plugin-working
     • /app/storage/cwd/plugins/persistence
     • /app/storage/cwd/plugins/plugin-root
   • Restart the plugin daemon service.
   • Reinstall the plugins from the marketplace.

This error typically occurs when plugin installation fails because Python dependencies cannot be installed within the default 120-second timeout period. If you encounter this error when making a POST request to a specific endpoint, ensure that the plugin is correctly installed and configured. Additionally, addressing any database synchronization issues by uninstalling and reinstalling the plugin can help resolve the error ^[1][2][3][4].
