SDK Setup

No response

Steps to Reproduce

1. Capture the error returned by useRouteError

export function ErrorBoundary() {
  const error = useRouteError();

  captureRemixErrorBoundaryError(error);
}

2. Trigger a remix 404 error:

No routes matched location "/daw/" 

3. The error tags look like a wrongly spreaded string:

Expected Result

The error message is displayed normally.

Actual Result

The error message is displayed like a spreaded string.

The root cause seems to be here:

When the event.data is a string, it will be spreaded into eventData as something like { 0: 'a', 1: 'b', 2: 'c' ... }, which scrambles the display of error data on the page.
