metaplex umi: Failed to send transaction Error: Simulation failed. Message: Transaction signature verification failure

FRONTEND:

On the frontend, the transaction is signed by the wallet wallet_pubkey.

if (window.solana && window.solana.isPhantom) {  try {    const connection = new Connection(url, "confirmed");    const transaction_array = Buffer.from(transactionBuildValue, 'base64');    const decodedTransaction = VersionedTransaction.deserialize(transaction_array);    const { blockhash } = await connection.getLatestBlockhash();    decodedTransaction.recentBlockhash = blockhash;    const signedTransaction = await window.solana.signTransaction(decodedTransaction);    const signature = await connection.sendRawTransaction(signedTransaction.serialize());    await connection.confirmTransaction(signature, 'processed');    return { success: true, signature };    console.log(signature);  } catch (error) {    console.error(error);  }}

I get an error when trying to confirm a transaction via wallet.
