This class seems to be duplicated in your project.

            // If these two options are not used it would work fine with PHP Unit and XDebug,
            // however it produces output to console under PhpDbg. So we need a couple of
            // tweaks to make it work predictably in both environments.

            // this one forbids Whoops spilling output to console

        $response = $this->createThrowableJsonResponse($throwable, $message, $status);

It seems like $message defined by $run->handleException($throwable) on line 64 can also be of type false; however, Limoncello\Application\ExceptionHandlers\BaseThrowableHandler::createThrowableJsonResponse() does only seem to accept string, did you maybe forget to handle an error condition?
