    I'm going to take a shot at this one myself taking into account the answer given by @Wader and the comments from @Tyler Crompton:

    app/Exceptions/Handler.php

    /**
     * Render an exception into an HTTP response.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Exception $e
     * @return \Illuminate\Http\Response
     */
    public function render($request, Exception $e)
    {
        // If the request wants JSON (AJAX doesn't always want JSON)
        if ($request->wantsJson()) {
            // Define the response
            $response = [
                'errors' => 'Sorry, something went wrong.'
            ];
    
            // If the app is in debug mode
            if (config('app.debug')) {
                // Add the exception class name, message and stack trace to response
                $response['exception'] = get_class($e); // Reflection might be better here
                $response['message'] = $e->getMessage();
                $response['trace'] = $e->getTrace();
            }
    
            // Default response of 400
            $status = 400;
    
            // If this exception is an instance of HttpException
            if ($this->isHttpException($e)) {
                // Grab the HTTP status code from the Exception
                $status = $e->getStatusCode();
            }
    
            // Return a JSON response with the response array and status code
            return response()->json($response, $status);
        }
    
        // Default to the parent class' implementation of handler
        return parent::render($request, $e);
    }

    you can easily catch err.response like this:

    axios.post().then().catch(function(err){
    
    
     console.log(err.response);  //is what you want
    
    };
