[FE] Day-of Check-in - Display Retry Message for CHIP 503 Timeout

[kanchanasuriya]

User Story

As a user, I want to see a relevant error message when there is a downstream service timeout failure so that I can retry again for appointment check-in. (Refer below snapshot for the current error message shown to the user)

Note: Pre-checkin workflow shows the relevant error message for the user to try again later.

User Workflow

• Given
  • Vista taking more time to process the request and the CHIP API gateway returns 503
• When I
  • try for appointment check-in
• Then I
  • should see a message to retry again instead of a message to reach out to a staff member

Backend Implementation

Currently vets-api returns 400 for CHIP API Gateway timeout status code 503 and FE cannot differentiate the underlying timeout issue from other errors from the service layer. Dialing up check_in_experience_504_error_mapping_enabled, vets-api will start sending 503 to enable FE for differentiating timeout errors from others.

Tasks

• Eng & UX discussion to determine what needs to happen when a timeout is received on each page
  • Do we retry?
  • Did the check-in happen or not?
  • What type of message do we want?

@loripusey should we see if we have capacity to pull this in for next sprint?
