Выполнение вернуло ошибку, пока tokenOfOwnerByIndexERC721

Question

Ошибка при попытке получить tokenId по индексу из учетной записи Matic Polygon Testnet

Код:

      matic.tokenOfOwnerByIndexERC721(
    '<account address>',
    '<my nft address>',
     0, {
       from: '<from account address>',
       gas: 150000
     })
     .then(console.log)

Это вызывает ошибку
