Normal plugin update

❌ Actual Behavior

This error typically occurs when the plugin dependency installation times out. The default Python environment initialization timeout (120 seconds) is often insufficient.

Try these solutions:

1. Increase the initialization timeout - Add to your .env file:

   PLUGIN_PYTHON_ENV_INIT_TIMEOUT=320
   

   Then restart with docker compose down && docker compose up -d

2. Configure a PyPI mirror (if you're on a slow network):

   PIP_MIRROR_URL=https://mirrors.aliyun.com/pypi/simple
   

3. Restart the plugin daemon to clear any stuck processes:

   docker restart docker-plugin_daemon-1

4. Check Docker resources - The "context canceled" error can also indicate insufficient memory/CPU allocation for your containers.

this is my .env about plugin set items
PLUGIN_PYTHON_ENV_INIT_TIMEOUT=600

Plugin Daemon side timeout (configure to match the API side below)

PLUGIN_MAX_EXECUTION_TIMEOUT=600

API side timeout (configure to match the Plugin Daemon side above)

PLUGIN_DAEMON_TIMEOUT=600.0

A solution to this problem has been found. Just delete the plugin, reinstall it, and that's it. No need to adjust any configuration items.

this is because golang context cancel

[dosubot]

This is a known bug that was fixed in PR #596. The root cause is that the HTTP request context is incorrectly reused for background plugin installation tasks—when the HTTP handler returns after sending a task ID, the request context is canceled, which immediately cancels the dependency installation command (uv sync), resulting in the "context canceled" error.

Solution: Update your dify-plugin-daemon to a version newer than v0.5.3. The fix has been merged into the main branch. If you're using Docker, pull the latest images that include this fix.

See issue #603 for more details on the bug.
