[deeleeramone]

Re-opened PR from, #6548

1. Why?:

   • Error with message creation where None was cast as a string.

   • Posthog Handler tests were failing.

2. What?:

   • exec_info[1] will be None instead of "None"

3. Impact:

   • Should allow "CMD" to bucketed.

4. Testing Done:

   • The logs tests now all pass.
   • Inspect locally
