AttributeError: 'Spendable' object has no attribute 'address'

[gitchand]

I used "create_signed_tx" from "network.tx_utils.create_signed_tx" to generate a groestlcoin transaction and gettting "AttributeError: 'Spendable' object has no attribute 'address' ".

Sorry for delay, I was on vacation for a bit. Can you give me a short program that reproduces the problem?

Try using network.tx.Spendable instead of pycoin.coins.bitcoin.Spendable. That may not completely fix it.

Note that when I run this code, I don't get the error, as create_raw_transaction is never called. Can you include the code that invokes it? Leaving out private keys, of course.

[gitchand]

tx_id = create_raw_transaction("1GtqAR9y5KuCEhB3uVZL8wosUHUQoYVhvh", "1GtqAR9y5KuCEhB3uVZL8wosUHUQoYVhvh", 110000, "*****", netcode="BTC")

Add the above line of code at the end and then run that code.

It looks like the problem is that WIF that you posted (which I removed just in case real money ends up backing it) does not correspond to the addresses. There is also a bug fixed in f611038 which will now raise the correct exception.

Let me know if this is enough to resolve your issue or if you need more guidance.
