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

  1. Verify the path exists before calling: Path(p).is_file()
  2. Use absolute paths built from the workspace directory rather than cwd-relative paths
  3. 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

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.
