Sometimes we get the following messages in the SRE bot:

Error parsing AWS event:

{"text":"🟥 GC Forms - Formulaires GC (https://forms-formulaires.alpha.canada.ca/) is **down** : [https://github.com/cds-snc/status-statut/issues/159"}](https://github.com/cds-snc/status-statut/issues/159%22%7D)

Look if it is possible to make this more user friendly or at least parse out the messages.
