Investigation: lm.legitimization_measure_serial_id is UNIQUE. kt.access_token is NOT UNIQUE, but created via random_bytes() and SHOULD be UNIQUE. -> check? lp.legitimization_process_serial_id is UNIQUE. kyc_attributes table lacks a UNIQUE constraint on legitimization_serial. => That could, theoretically, be one cause for multiple results. |
