CPI fails with Cross-program invocation with unauthorized signer or writable account

i'm facing a weird issue. I'm trying to transfer token (2022) from a pda to a user token account.The code looks like this:

    let transfer_checked_discriminant: u8 = 0x0c;  let amount: u64 = 1;  let decimals: u8 = 0;  let accounts = vec![      AccountMeta::new(ctx.accounts.pda_token_account.key(), false),       AccountMeta::new_readonly(ctx.accounts.mint.key(), false),                   AccountMeta::new(ctx.accounts.seller_token_account.key(), false),          AccountMeta::new(ctx.accounts.pda_token_authority.key(), true),                      AccountMeta::new_readonly(ctx.accounts.hook_program.key(), false),      ];  let mut data = vec![transfer_checked_discriminant];    data.extend_from_slice(&amount.to_le_bytes());         data.push(decimals);                                 let instruction = Instruction {      program_id: ctx.accounts.token_program.key(),      accounts,      data,  };  solana_program::program::invoke_signed(&instruction,&[          ctx.accounts.pda_token_account.to_account_info(),          ctx.accounts.mint.to_account_info(),          ctx.accounts.seller_token_account.to_account_info(),          ctx.accounts.pda_token_authority.to_account_info(),          ctx.accounts.hook_program.to_account_info(),       ],      signer_seeds,  )?;

and the error is "ddKnNBKgdFQzqWLrmnxL1SHSsQU89jLeW9oEQiWp5r3's writable privilege escalated" ddKn is the authority of the PDA. (pda token auhority in my code).The signer seeds should be correct since when i use Pubkey::find_program_address i get the right public key.The account (pda authority) should be sent as a signer since i use "true" in the AccountMeta, and i use invoke_signed.

So i don't get why i have this error...Here is a failed transaction example: https://explorer.solana.com/tx/4gZfKHavQR6Zx48kqYPMNRVUEsvzHpHBe7J4o74NLjP98LhaWMpCgsi5kAy32ECSpWrFQrqfFMz8bYBeczyFaMe8?cluster=devnet

Also, i'm pretty sure the code used to transfer is correct since i used it to send the nft to the PDA, and it worked properly. The only difference was that i used invoke and not invoke_signed because the authority was aleady signing the transaction (it was a user).

Any idea ?
