Summary from the Slack thread:

1. user opens VA.gov SM tool[a]
2. user starts new message
3. user attaches file that will cause the SM backend to error out
4. user clicks send
5. user does not see error
6. message is not sent
7. User is returned to the message draft

167 instances were found in Datadog in the last 30 days. Patrick and team did an out of band deployment to return an error to the user. Post-mortem to follow.
