Hi Christinad,
1. Please make sure whether the JE is created or not. You can inquire this, based on the accounts, or voided batch number.
2. If you are confirmed that JE is not created, then create JE and close the issue first.
3. To find out the cause of the issue, make sure is there any customization on that window. If so, analyze the scripts of the customization and make sure everything written properly.
4. If not, is might be happened by power disconnection or LAN disconnection between UI and server while posting.
