Long pytest makers make report portal status:interrupted
When i use this on a test:
@pytest.mark.required_options('MACHINE_TYPE=100/101/102/103/104/105/106/107/108/110/111/112, USE_FAM_HLM_SENSOR=1, USE_FAM_OPTION=1, USE_HOLE_LENGTH_MEASURE=1)

report portalt get status:interrupted and this error:
INTERNALERROR> reportportal_client.errors.ResponseError: 4001: Incorrect Request. [Field 'attributes[].value' should have size from '1' to '128'.]

the @pytest.mark.required_options are too long, But are there anything you can do, or do we have to live whit this?
