Error: sendMessage: Keystore not found

[shravanandoria]

this problem comes while trying to call mint function in the smart contract & this error gets thrown

const mint_nft = async (provider) => { const json = { type: "Basic NFT", name: "Sample Name", description: "Hello world!", preview: { source: "https://venom.network/static/media/bg-main.6b6f0965e7c3b3d9833b.jpg", mimetype: "image/png", }, files: [ { source: "https://venom.network/static/media/bg-main.6b6f0965e7c3b3d9833b.jpg", mimetype: "image/jpg", }, ], external_url: "https://venom.network", };

const contr = new provider.Contract(
  collectionAbi,
  collection_address_testnet
);

const res = await contr.methods
  .mintNft({ json: json })
  .send({ from: new Address(signer_address) });

console.log(res);

};
