ContractNotFound: No contract deployed at
Question:
I have been involved in the chainlink bootcamp and trying to finishing the final ‘Exercise 3: Putting it all together’.
However, I am stuck running:
brownie run scripts/price_exercise_scripts/01_deploy_price_exercise.py --network kovan
ContractNotFound: No contract deployed at 0xF4030086511a5bEEa4966F8cA5B36dbC97BeE88c
Printed contract_type._name
is a mock address returned from `MockV3Aggregator which also doesn’t make sense, why the code calls this logic.
def get_contract(contract_name):
contract_type = contract_to_mock[contract_name]
if network.show_active() in NON_FORKED_LOCAL_BLOCKCHAIN_ENVIRONMENTS:
if len(contract_type) <= 0:
deploy_mocks()
contract = contract_type[-1]
else:
try:
contract_address = config["networks"][network.show_active()][contract_name]
contract = Contract.from_abi(
contract_type._name, contract_address, contract_type.abi
)
except KeyError:
print(
f"{network.show_active()} address not found, perhaps you should add it to
the config or deploy mocks?")
print(
f"brownie run scripts/deploy_mocks.py --network {network.show_active()}"
)
return contract
I am struggling to understand this error message, should this command not be deploying contracts? I.e they should already already exist on the kovan network?
Any insights welcome!
Answers:
Problem – I was using the ethereum mainnet address instead of the correct kovan network address for btc / usd price.
Changing the btc_usd_price_feed
value to 0x6135b13325bfC4B00278B4abC5e20bbce2D6580e
in the config.yml fixed this issue for me.
Because address of ganache is reset(by close and open again) and brownie use its own files which is gone
Remove files and directory in build/deployments
solve for me.
Delete .openzeppelin/unknown-YOUR-NetworkId.json !!!
This happens especially at deploying upgradeable contracts into Parachain EVM.
