NFT marketplace boilerplate error 400 after deploy

Hi! I set up NFT marketplace boilerplate on local server and it looks ok - https://prnt.sc/26pn3ud

But when I deployed to hosting (netlify), the functionality stopped working and often nothing is displayed except for the site header.

Here are the errors I see in the console: https://prnt.sc/26pn59b

Also, when opening a domain (meta-nft.games), a subdomain is automatically added (meta-nft.games/NFTMarketPlace)

And if you refresh the page - also a 404 error appears

Also, in the “my collection” section, NFTs are not displayed for me and I cannot test the functionality.

And please tell me how to add the ability to create NFTs for each user.
Thanks in advance.
