In my jira "components" field is required for create issue. To a job I add step "New Tickets To Submit", fill main fields and add new "field value" with setted "Name of the field to set" = "components". For "The field value to set" I used many diffenent options: Component_name, "Component_name", [

{"name":"Build server"}

], [

{\"name\":\"Build server\"}

] and many others. In the results of creating issue with different options I always get an error "ERROR: Build step failed with exception
RestClientException{statusCode=Optional.of(400), errorCollections=[ErrorCollection{status=400, errors=

{components=Component/s is required.}

, errorMessages=[]}]}"

I found next links which describe how to files components should be filled in the REST API.

Please add ability to setting components in plugin or describe documentation "how use it", if it works now.
