TypeError: Blob data is not supported for legacy transactions.

What happened?

I got this error.

TypeError: Blob data is not supported for legacy transactions.

Code that produced the error

account.sign_transaction() doesn't take a private key since the account object has the private key. You just need to pass in the transaction.

account.sign_transaction(txn)
