When creating a task, I have an error message that is not helping

{

"err": "Invalid Value, expected an object { add?: string[], rem?: string[] }",

"ECODE": "FIELD_375"

}

FIELD_375 doesn't match anything : it's not a custom field ID, it's not a label, it's nowher to be found on the documentation.

I would like to understand what field is problematic with an ID or a label in your API error message
