I created a candymachine v3 with sugar and I am trying to mit using the following code:

 const { nft } = await metaplex.candyMachines().mint({
  candyMachine,
  collectionUpdateAuthority: candyMachine.authorityAddress,
});

setNft(nft);

The following error is returned:

Error: Signature verification failed

Can anyone help me? Thanks.

  • Can you provide more detail about the other parts of your setup? You can also try referencing this MintNFTs.js page from the mint-ui-example repo provided by metaplex: github.com/metaplex-foundation/js-examples/blob/main/…

  • Reference has already been made to the MintNFTs.js page from the mint-ui-example repo provided by metaplex. Everything else works except this function where you try to minify an Nft from a v3 candy machine created with sugar cli. I should also add that this problem has only been occurring for a few days, before that the mint function worked perfectly.

Same issue is for me using this example from Metaplex (https://github.com/metaplex-foundation/js-examples/tree/main/mint-ui-example)

The issue is with the WalletIdentity-Provider because when I use KeyPairIdentity-Provider I am able to mint the NFT on the backend.

Any help is appreciated. I am using phantom wallet with this which is connected on DEVNET cluster. Tried to add custom signer option with the feePayer but no success.
