Cannot build transaction with web3/Ganache, Error: Method eth_maxPriorityFeePerGas not supported #8

Closed shonendumm closed 2 years ago

Hi Patrick, thanks for the wonderful solidity tutorial.

I got stuck at https://youtu.be/M576WGiDBdQ?t=14423

the part where we're building a transaction with web3 and connecting to Ganache.

I tried to print(transaction) but got the errors below, specifically 'Method eth_maxPriorityFeePerGas not supported.'

By any chance, would you know how to resolve this?

wow, it's like we bumped into each other while walking on the road :) same mistake, at the same time. I need help too.

I got stuck in the same place. I guess the problem is caused by the new version of web3py.

Someone has found the answer here: https://stackoverflow.com/questions/70051896/python-web3-and-ganache-error-method-eth-maxpriorityfeepergas-not-supported/70053558#70053558

Add "gasPrice": w3.eth.gas_price to

transaction = SimpleStorage.constructor().buildTransaction( { "gasPrice": w3.eth.gas_price, "chainId": chain_id, "from": my_address, "nonce": nonce, }

Thank you all so much for making this issue!

Thank you all so much for using the repos and being apart of the open sourced community 🙏

You are doing the course right coming here. Sometimes, things change and update. Knowing where/how to get the answer sometimes is more important that knowing the answer yourself.

Great work all!
