solidity - Metadata is not showing on opensea

2022-10-04 11:53 View 13

i am trying to develop a nft mint daap. i deploy the erc 721 contract on bsc test net(0x5542bD28FD0D8c22D4AC7D51E62735Ac32d32374) The mint function is working but the metadata is not showing on opensea test net. for metadata and image i am using pinata, here is the link for metadata

https://gateway.pinata.cloud/ipfs/Qmcchbbm2R6CdiwsYbcoLPcY7PSi7yska9HzDCvK977mMU.

the steps i am following: deploy the token, enable public mint , setting the tokenUri.
