# Async and Error Handling for 674
This is a brief overview of BGS::SubmitForm674Job in terms of async calls and error handling:
- Raises Invalid674Claim error if claim data is not valid. Validity is defined as follows:
- SSN can’t be blank
- Dependent application can’t be blank
- Veteran address can’t be blank
- Submit 674 (BGS::Form674#submit)
- BGS::Service methods called: #create_proc, #create_proc_form, #create_note, #update_proc
- #create_note has a rescue block that raises a 'BGS_686c_SERVICE_403’ backend exception and re-thrown for SubmitForm674Job to catch, but doesn’t look like any notification is sent to the user at this point.
- If 674 job succeeds:
- Deletes in progress form
- Async send VANotify::ConfirmationEmail to user
- If any exception is caught
- revert in progress form data
- DependentsApplicationFailureMailer#deliver_now to user
