What seeds should I use in `invoke_signed()` for PDA derived via `create_with_seed()`

Question

I have a PDA generated with:

const SEED: &str = "My Seed";
let pda = Pubkey::create_with_seed(program_id, SEED, &owner_id).unwrap();

Where program_id and owner_id are some fixed Pubkey's.

I want to call this:

invoke_signed(
    &my_instruction,
    &[...], \\Slice of AccountInfos, pda is among them
    &[&[...]],\\Seeds for accounts to be signed
)

Then I pass SEED.as_bytes()a as a seed, I get InvalidSeed error. What to use in this field?

Answer 1

This isn't working for you because create_with_seed doesn't generate a PDA! Use Pubkey::find_program_address if you want that.

So your code will look like:

const SEED: &[u8] = b"My Seed";
let (pda, bump) = Pubkey::find_program_address(&[SEED], program_id);
