ERROR: Error during SonarQube Scanner execution
ERROR: The ‘report’ parameter is missing
ERROR:
ERROR: Re-run SonarQube Scanner using the -X switch to enable full debug logging.

The error message doesn’t come from the python analyzer but from the scanner.
The analysis went fine but the scanner failed to send to analysis report to the server.
Can you please check the logs on the server side?
