CRAWL_TASK_ERROR

Error message

配置文件不存在

What it means

Thrown by _load_crawl_config in the system tools when config/config.yaml does not exist under project_root. This is a hard prerequisite: the hot-list crawl tasks read platform definitions, credentials, and feature toggles from this file before doing anything else.

Solutions

1. Create config/config.yaml under the project root (copy from the repo's example config if provided)
2. Verify project_root points at the actual repository when launching the MCP server from another directory
3. In deployments, mount/bake the config file into the image or volume

Example fix

# before: file missing
# $ ls config/
# (empty)

# after
 cp config/config.example.yaml config/config.yaml
 # then edit platforms/credential entries

When it happens

Trigger: Running a crawl-trigger MCP tool in a checkout where config/config.yaml was never created (usually it is gitignored and must be copied from an example), or when project_root is mis-detected (launched from a different working directory).

Common situations: Fresh clone without running the setup step that copies config.example.yaml; deploying a container without mounting the config directory; CWD-dependent project_root resolution.
