HookFileImportError

The Cause

A file under .thymian/sampler/hooks/ could not be imported at all. Usually a syntax error, or an import of a module that is not installed.

What to do

The error names the file, relative to the hooks directory, and carries the underlying failure as its cause — run with --debug to see it.

Unlike an unresolved hook, this is not something the sampler can report alongside others: the scan could not finish, so it fails when the API description is published rather than when a run starts.

Note the loader skips declaration files (*.d.ts) and dot-directories, so neither of those can cause this. If you keep hand-written types beside your hooks, a .d.ts name is the way to have them ignored.
