No file sent.

Error message

No file sent.

What it means

A plain Exception (not UserError) raised by _import_zipfile when the module_file argument is falsy — i.e. the caller invoked the import API without attaching a file. Because it is a bare Exception, it typically surfaces as a traceback rather than a friendly UI message; it almost always indicates a caller bug or an empty upload.

Solutions

1. Attach a valid ZIP file before calling the import (validate the upload client-side)
2. Check the field name mapping between your form/RPC payload and module_file
3. Guard the call: if not module_file: skip or show a validation message instead of invoking the API

Example fix

# before
env['base.import.module']._import_zipfile(module_file=None)  # Exception('No file sent.')

# after
if not module_file:
    raise UserError(_('Please select a module file to import.'))
env['base.import.module']._import_zipfile(module_file=module_file)

if not module_file or not getattr(module_file, 'read', lambda: b'')():
    raise UserError(_('Please attach a module file.'))
env['base.import.module']._import_zipfile(module_file=module_file)

When it happens

Trigger: Calling _import_zipfile(module_file=None) / submitting the import wizard with no file selected, or an RPC payload where the 'file' key is missing or empty.

Common situations: Front-end form submitted before a file was chosen; HTTP file field name mismatch (server reads 'module_file' but form posts 'file'); base64 field left empty on base.import.module record.
