[ConsyConsy]

When I try to create a Contact, with a linked Account that has Account_Name formed of digits, i.e. "778" I receive the following status code: 202. Error message "You do not have sufficient authorization to associate this record. Contact the administrator."
exception code: INVALID_DATA
error details: {"api_name"=>"Account_Name"}
