MCAZB040 Job 異常終了 - メール変換受付 (java.lang.NumberFormatException: null)

This log message indicates an abnormal termination of the MCAZB040 job. The function ID is MCAZB040, which is responsible for mail conversion reception. The error message is "java.lang.NumberFormatException: null". \n\nThe error occurs at line 164 of the MCAZB040Job class, where it tries to parse a null value as a Long. This leads to a NumberFormatException. \n\nThe error is then propagated to line 101 of the MCAZB040Job class, which executes the job. It is further propagated to line 50 of the MCAZB040Batch class, which runs the batch job. \n\nThe error is finally caught by the SpringApplication class in the Spring Boot framework, which handles the execution of the batch job. The error is logged and the application terminates. \n\nTo resolve this issue, you need to investigate why a null value is being passed to the Long.parseLong() method. You may need to add proper null checks or handle null values appropriately to avoid the NumberFormatException.
