panic in AddPlanConvoMessage: %v %s

Error message

panic in AddPlanConvoMessage: %v
%s

What it means

Recovery guard inside AddPlanConvoMessage's goroutine: a panic occurred while persisting the convo message; the panic value and stack are logged and converted into this returned error instead of crashing the server.

Solutions

1. Read the logged stack trace to find the panicking code path
2. Check for nil fields on the ConvoMessage being inserted
3. Fix the underlying nil-deref/bug; the recover is only a safety net
