Faulty build UI doesn't display error information

[coderabbitai]

Problem

When a deployment build fails, the UI doesn't display any error information or feedback to the user about what went wrong.

Context

This issue was identified during testing of the deployment build screen (PR #5042). This appears to be more of a backend issue than a frontend one.
