</div>

when passing Txn accounts to InnerTxn field, as

```auto
...
TxnField.accounts: [Txn.accounts[1]]
....

```

I receive the following error:

```auto
RUNTIME_ERR1048: execution of itxn_field Accounts failed. Message: Field Accountsi is invalid.

```

What might be causing this?

Hi tcduqk,

Can you look at the teal source file? I’m guessing at some point an `i` was added at the end of the valid `Accounts` field?

I take it back, the misspelled Accounts field would not make it past assembly. Are you using some other teal interpreter or alternate AVM implementation?
