### Describe the issue

I've deployed successfully my backend to a serverless cloud service, but, unlike the local version, in the hosted app I'm getting an unreadable response rather than JSON as you can see below.

`"�\b�T�r�8���r�i�.~����FH�!�\t�01C���\\��*Y�T��e�{�=��{��NgY?_�]��Aӝ�.yQw?k/?��۬=�|���<��#�dd3)��6���l2\nJ]X��������e��^�?\r|�H`

### Example Code

```js
app.get('/api/get-my-books', (req, res) => {

    const address = req.query.address;
    const chain = "polygon";

    const options = {
        method: 'GET',
        url: `https://api.nftport.xyz/v0/accounts/${address}`,
        params: {
          chain: chain,
          include: 'metadata',
          contract_address: process.env.REACT_APP_DROP_CONTRACT
        },
        headers: {
          'Content-Type': 'application/json',
          Authorization: process.env.REACT_APP_NFT_PORT
        }
      };
      
      axios.request(options)
      .then((response) => {
        res.json(response.data);
      })
      .catch((error) => {
        console.error(error);
      });
});
```
