Syntax error in workspace module '{name}' ({source_path}):\n
Error message
Syntax error in workspace module '{name}' ({source_path}):\n{traceback.format_exc()} What it means
Thrown by g4f's .pa.py sandbox loader (pa_provider.py) when Python's compile() raises SyntaxError on a workspace module's source. The original syntax error and full traceback are embedded in the ImportError message so the offending line is visible. It fires before any execution of the module.

Solutions
- Read the embedded traceback in the ImportError message — it names the line and column of the syntax error; fix that line.
- Validate locally first: python -m py_compile module.pa.py before uploading.
- Re-upload the complete file if truncation is suspected (check the file end).
- Replace smart quotes/dashes with ASCII equivalents if the source was pasted from a rich-text source.
Example fix
// before (module.pa.py)
def run(x)
return x * 2
// after
def run(x):
return x * 2 Defensive patterns

raise Prevention
- Run python -m py_compile on .pa.py files before uploading.
- Reject partial/empty uploads by checking the file parses.
When it happens
Trigger: Uploading a .pa.py workspace module containing invalid Python — unbalanced brackets, bad indentation, Python-2-style print, f-string typos, or a file saved mid-edit / truncated by an upload limit.
Common situations: AI-generated tool code edited into a workspace with a missing colon or paren; copy-paste losing leading spaces (IndentationError is a SyntaxError subclass); encoding issues (smart quotes pasted from chat clients); partial file writes during concurrent edits.
