change the mintAuthority

Question

I encountered an error while attempting to change the mint authority. Currently, the mint authority is the same as my token address. I intend to change it to null or according to the wallet address. However, when I ran the script, I received a "signature verification failed" error.

TokenAddress: FS32hKLJVEN9NoaGvS4NpumuwcrDkmJ5Mt5CYyiXfdxj Authority: FS32hKLJVEN9NoaGvS4NpumuwcrDkmJ5Mt5CYyiXfdxj

 const transactionSignature = await setAuthority(
        connection,   //connection
        userWallet,   // wallet Address
        mintPubkey,   //tokenMintAddress
        mintPubkey, // current authority
        AuthorityType.MintTokens,
        null //new authority
    )

Answer 1

The current authority has to be included as a signer.

You're specifying that the mintPubkey is also the current mint authority on the mint account. This means you would need to have the keypair that was used to create the mint account and include it as a signer.

If the mint address is a PDA, then you would need to add an instruction to your program invoking the setAuthority instruction via a CPI and sign using the PDA.
