When accessing the v3.1 GET /transactions endpoint, we are receiving an invalid Data/Transaction/MerchantDetails/MerchantCategoryCode. The specification states that this field must be of type Min3Max4Text, however we are receiving just a single character "2".
Example response (note: other fields omitted for brevity):
We are unable to accurately parse the response, as we are expecting the MerchantCategoryCode to be of length 3-4.
We are unable to accurately map this MCC to one specified by the ISO 18245 standard, as it is non-compliant with that spec.
