When the Giftcard Hub receives any error, it ends up returning a 500 error to the user. This occurs because errors are handled in the Giftcard System code.

This behavior can happen across different requests, regardless of the HTTP verb. The root cause is that when the Giftcard System does not find content in the response, which is common in 4xx and 5xx responses, it clears the content from memory. Later, when the code tries to access this element again, it has already been disposed of, resulting in the following error message:

Cannot access a disposed object. Object name: 'System.Net.Http.StreamContent'.

With this, the user does not have clear information about what happened, which makes troubleshooting much more difficult.
