Web3 Contract Deployment Error - Execution Reverted
I am encountering an issue while deploying a smart contract using Web3. The deployment process triggers an error leading to contract execution being reverted.
Problem Description: Upon attempting to deploy a smart contract using Web3, the deployment process fails, and the transaction is reverted. The error message suggests a VM Exception during transaction processing with the specific message: "revert."
Code =
import solcx
from web3 import Web3
import json
def compile_source_file(file_path):
compiled_file = solcx.compile_files([file_path],
output_values=["abi", "bin-runtime"],
solc_version="0.8.0")
return compiled_file
def deploy_smart_contract(compiled_details):
abi = next(iter(compiled_details.values()))["abi"]
bytecode = next(iter(compiled_details.values()))["bin-runtime"]
w3 = Web3(Web3.HTTPProvider("HTTP://127.0.0.1:7545"))
account = w3.eth.accounts[0]
Greeter = w3.eth.contract(abi=abi, bytecode=bytecode)
tx_hash = Greeter.constructor().transact()
tx_receipt = w3.eth.wait_for_transaction_receipt(tx_hash)
contract = w3.eth.contract(
address=tx_receipt.contractAddress,
abi=abi
)
greeting_value = contract.functions.greet().call()
print("Greeting Value:", greeting_value)
sol_file_path = "contract.sol"
sol_compiled_file = compile_source_file(sol_file_path)
deploy_smart_contract(sol_compiled_file)
Error -

web3.exceptions.ContractLogicError: execution reverted: VM Exception while processing transaction: revert
I expected the smart contract deployment to be successful without encountering any exceptions. The goal was to have a fully functional contract deployed on the specified network with the given ABI and bytecode.
I'm seeking assistance in understanding and resolving the VM Exception during transaction processing, specifically the "revert" message.
