Hi,
I’m trying to add a comment to my report following the API here:
https://docs.greenbone.net/API/OMP/omp-7.0.html#command_modify_report

but it does not seem to actually modify the report:

    omp --xml="<modify_report report_id=\"5414b28d-849e-466e-a781-1548f2e1081a\"><comment>test</comment></modify_report>"
    <modify_report_response status_text="OK" status="200"></modify_report_response>
    omp --xml="<get_reports report_id=\"5414b28d-849e-466e-a781-1548f2e1081a\"/>"
    <get_reports_response status_text="OK" status="200"><report id="5414b28d-849e-466e-a781-1548f2e1081a" format_id="a994b278-1f62-11e1-96ac-406186ea4fc5" extension="xml" type="scan" content_type="text/xml"><owner><name>admin</name></owner><name>2019-09-19T12:40:39+02:00</name><comment></comment><creation_time>2019[...]

The comment field remains empty. What am I missing here?

Please note that the OMP protocol itself, the OMP API documentation as well as the omp command line client are deprecated.

The replacements are (See e.g. Omp library - Greenbone Management Protocol (GMP) - Greenbone Community Forum as well):
