3 years ago Hi @jjhesk. I tried to reproduce this today in a few different ways and I was not able to. I'm assuming this is in a method within a class since you have self references to the object. Have you tried breaking this down into a simpler form and interacting with the library directly first before making an OOP abstraction? It might help to debug your situation without knowing any more of the inner workings of your class.
I would maybe suggest using a fresh python virtual environment with a fresh install of web3 and interacting with your contract in a bit simpler way and abstracting from there if that works.
The following can be used as a guide to test while running geth in dev mode, thus connecting to http://127.0.0.1:8545.
run geth in dev mode from a new terminal window:
$ geth --http --devGet your abi and bytecode from your compiled solidity the way you currently are (using solc). It doesn't look like you are having issues within this part. Put your working code for extracting those values below and test this:
from web3 import Web3
# Get your compiled solidity however you are getting it, extracting `abi` and `bytecode`...
# This part seems to be working for you.
w3 = Web3(Web3.HTTPProvider("http://127.0.0.1:8545"))
your_contract = w3.eth.contract(abi={abi}, bytecode={bin})
_transaction = your_contract.constructor().buildTransaction()
acct = w3.eth.account.create()
_transaction['nonce'] = w3.eth.getTransactionCount(acct.address)
_transaction['to'] = None
_transaction['from'] = acct.address
signed = w3.eth.account.sign_transaction(_transaction, acct.key)
txHash = w3.eth.send_raw_transaction(signed.rawTransaction)
tx_receipt = w3.eth.waitForTransactionReceipt(txHash)The only issue you will see with this example is that you will not have funds to send_raw_transaction() (which is the preferred method over sendRawTransaction(). The latter is deprecated. You may want to update that on your sample you sent over). You can use an account address that has funds if you'd like to test further but if you get here you will have gotten past the sign_transaction() issue you reported.
I have tested all the way through this with a funded account in a few different ways and was not able to reproduce what you are seeing so I am closing this ticket. If you are still having issues, please reopen. I do hope this helps you troubleshoot.
