Description
When configuration is provided that isn't correct, the outbox event router code can hit a NPE and such errors are very ambiguous and do not help the user diagnose their mistake. For example, if the payload field doesn't match any fields in the structure, a NPE will occur rather than informing the user that there was a problem with the payload configuration.
