Cause
The subjects list is not a list, exceeds 50 references, or a reference is not an object, has an unknown kind, no key or several keys, a key that does not belong to its kind, or a value in an invalid format. details.reason gives the cause (not_a_list, too_many, not_an_object, unknown_kind, exactly_one_key, unknown_key or invalid_value) and details.index, the position of the reference.
What to do
Send at most 50 references, each with its kind and exactly one of the keys in the Business references table, in the format of each type.
