Running wheels-hotwire tests results in blank page with `Errors -1`

[zainforbjs]

Describe the bug
After installing the wheels-hotwire package and attempting to run its tests, the test page renders a blank screen displaying only:

Errors
-1

No additional error details or stack trace are shown, making it difficult to diagnose the failure.

To Reproduce
Steps to reproduce the behavior:

1. Install the wheels-hotwire package in a Wheels application
2. Run or open the package tests
3. Observe the blank page with:

Errors
-1

Expected behavior
The tests should:

• Run successfully
  or
• Display meaningful error output and stack traces if failures occur

Additional context
The issue may be related to:

• Test bootstrapping/setup failure
• Silent exception handling
• Missing dependency or configuration
• Error rendering failure in the test runner

The current output (Errors -1) is not actionable and does not provide enough debugging information.
