Approving journal giving FRM-40735: WHEN-BUTTON-PRESSED trigger raised unhandled exception ORA-06502

Good day folks

I am getting this error 'FRM-40735: WHEN-BUTTON-PRESSED trigger raised unhandled exception ORA-06502.' on clicking the approve button on a journal batch. There are no personalizations on this form.

I have applied this to the environment, but it did not resolve the issue:

telnet to your server as applmgr
- set the environment variables to the RUN env.
