Calling Yahoo Finance API in RapidAPI via axios returns error 500

I’m subscribed to the Yahoo Finance API via RapidAPI and I’m calling the API using axios like this:

 const apiKey = ref([MY API KEY])
 const apiURL = ref('https://yahoo-finance127.p.rapidapi.com')

 const headers = ref({
   'x-rapidapi-key': apiKey.value,
   'x-rapidapi-host': apiURL.value
 })

 axios.get(apiURL.value + '/price/NVDA', { headers: headers.value })
   .then(response => console.log(response.data.data))
   .catch(error => console.error(error.message))

Any idea why this is returning an error 500?
