### Problem Statement

The top exception is the generic one, which is basically an error log message, and the bottom one is the actual underlying exception that caused this alert to be fired:

### Solution Brainstorm

Is there any way to include all the nested exception names & messages in the Slack alert?

Those error logs might sometimes hide multiple different exception types under them and cause new issues to be missed, therefore mistaken for more occurrences of older errors.
