In laravel 9 app with axios 0.25 when making request to server

axios.post(route('frontend.get_block_cms_item'), filters)
    .then(({data}) => {
        main_page_contact_us_title.value = data.cMSItem.title
        main_page_contact_us_text.value = data.cMSItem.text
    })
    .catch(error => {
        console.error(error)
    })

I use code when item is not found :

    public function get_block_cms_item(Request $request)
    {
        $key     = $request->key;
        $cMSItem = CMSItem
            ::getByKey($key)
            ->getByPublished(true)
            ->first();
        if (empty($cMSItem)) {
            return response()->json([
                'message' => 'CMS Item with key "' . $key . '" not found !',
                404
            ]);
        }

but code .then(({data}) => is called and I got run time error :

typeError: Cannot read properties of undefined (reading 'title')

I expected that

.catch(error => {

must be run and I will not get error...

How that can be fixed ?

Thanks in advance!
