Creating Metaplex metadata from an Anchor program?

Question

I want to create a token entangler that pushes the minting to the user instead of requiring pre-minting by the owner. For that, I'm creating an Anchor program that first mints a collection token and its metadata, before allowing holders of the original collection to entangle their token (transfer OG token + mint entangled version and create metadata).

My problem is that I keep getting a NotEnoughAccountKeys error. My logs look like this for the failing instruction:

Program log: Instruction: Create Metadata Accounts v2
Program log: Error: NotEnoughAccountKeys
Program metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s consumed 3932 of 103222 compute units
Program metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s failed: insufficient account keys for instruction

Program 6UnTeNe18TsxBPJfLYxRYUnWyUfALuxD1e23gMswxSN8 failed: insufficient account keys for instruction

The call that triggers this log is the following:

let original_metadata =
    Metadata::from_account_info(&ctx.accounts.original_collection_metadata).unwrap();

let authority_bump = *ctx.bumps.get("entangler_authority").unwrap();
let authority_seeds = &[AUTHORITY_SEED.as_bytes(), &[authority_bump]];
let authority_signer_seeds = &[&authority_seeds[..]];

// Mint the token
let mint_ctx = CpiContext::new_with_signer(
    ctx.accounts.token_program.to_account_info(),
    MintTo {
        mint: ctx.accounts.entangled_collection_mint.to_account_info(),
        authority: ctx.accounts.entangler_authority.to_account_info(),
        to: ctx
            .accounts
            .entangled_collection_mint_token_account
            .to_account_info(),
    },
    authority_signer_seeds,
);
token::mint_to(mint_ctx, 1)?;

        ctx.accounts.rent.to_account_info(),                          // Rent
    ],
    authority_signer_seeds,
)?;

Looking at metadata creation on an explorer, I can see that these are the correct accounts needed, other questions have similar accounts, I looked at Cardinal's code but I still can manage to get it to work

Answer 1

Turns out the error was setting the creator verified to true
