Trying to fetch some SPL tokens metadata results in a CORS error

[triplenick]

When I try to fetch some SPL tokens it might result in the CORS error:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://bafkreifmg4cdxkke4z6fbmkpryyi56raq7bytjojteg5hhhubohcy6ycnq.ipfs.nftstorage.link/. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 500.

Some tokens are being fetched without any errors, but the other ones might throw the error.

Requests are being sent from http://localhost:5173/ which is a typical local webdev server.

Example of a token which is fetched without any errors: M5sJ7XaEsGF5M3FtidFEBE7Wghqz4iocs85yQBNUPX2
Example of a token with errors: CzHvRSSgYddADVnrEBa2b574qbQJ2vGALoREqPyDEL6A

Im using a paid rpc provider

and the following code:

    const metaplex = Metaplex.make(connection);
    const mintAddress = new PublicKey(address);

    const metadataAccount = metaplex
      .nfts()
      .pdas()
      .metadata({ mint: mintAddress });

    const metadataAccountInfo = await connection.getAccountInfo(metadataAccount);

    if (metadataAccountInfo) {
      try{
        const token = await metaplex.nfts().findByMint({ mintAddress: mintAddress });
        console.log(`${JSON.stringify(token)}\n\n${token.symbol} | ${token.mint.decimals} | ${token.name}`)
        return{
          name: token.name,
          symbol: token.symbol,
          decimals: token.mint.decimals
        }
      }catch (e) {
        console.log(`fetchTokenMetadata: ${e}`)
      }
    }
