{ "code": -1, "message": "Duplicate key ""} when using /report/webinars/{webinarId}/participants with optional parameter 'include_fields'

Description
When using /v2/report/webinars/{webinarId}/participants with the optional parameter ‘include_fields’ (and the page_size parameter) after several successful calls using the next_page_token suddenly I get an error. If I omit the ‘include_fields’ parameter everything works as expected.

The value for ‘include_fields’ is: registrant_id

Error
{

    "code": -1,

    "message": "Duplicate key **key**"

} 

(Can send key via DM if needed)

Which Endpoint/s?
/v2/report/webinars/{webinarId}/participants
