PA provider file not found: {file_path}
Error message
PA provider file not found: {file_path} What it means
Raised by load_pa_provider when the given path does not exist (Path.exists() is false). This is the entry point that loads a sandboxed PA provider file, so it is the first sanity check before extension and execution checks. The message embeds the exact path for quick diagnosis.
Source
Thrown at g4f/mcp/pa_provider.py:746
The file is executed inside the safe sandbox. The module is expected to
define a class named ``Provider``; if that name is absent the first class
with a ``create_completion`` or ``create_async_generator`` attribute is
returned instead.
Args:
file_path: Path to the ``.pa.py`` file.
Returns:
The provider class, or ``None`` if none could be found.
Raises:
FileNotFoundError: If *file_path* does not exist.
ValueError: If *file_path* does not end with ``.pa.py``.
RuntimeError: If the file fails to execute.

Solutions
- Verify the path exists before calling: Path(p).is_file()
- Use absolute paths built from the workspace directory rather than cwd-relative paths
- Re-register/re-point the provider after moving or renaming the file
Example fix
# before
load_pa_provider('myprov.pa.py') # relative, wrong cwd
# after
load_pa_provider(get_workspace_dir() / 'myprov.pa.py') Defensive patterns
Strategy: validation
Validate before calling
from pathlib import Path
p = Path(file_path)
assert p.is_file(), f"missing PA provider file: {p}" Try / catch
try:
provider_cls = load_pa_provider(path)
except FileNotFoundError:
provider_cls = None # log and skip / re-register with correct path Prevention
- Build provider paths from the workspace root, never from cwd
- Validate is_file() before loading, especially for user-registered paths
- Re-check registered provider paths after workspace moves
When it happens
Trigger: Calling load_pa_provider with a typo'd path, a relative path resolved against the wrong working directory, or a file that was moved/deleted after registration.
Common situations: MCP tool invocations referencing a stale workspace path; scripts run from a different cwd so a relative path no longer resolves; provider files renamed from .py to .pa.py leaving old references.
