This error means that the smart contract was not deployed successfully.

both Ethereum and Parity use the same DB, there shouldn't be any differences in evm_utils.cc

I have checked the code , there was no differences in between Eth and parity .But I print the return information of "lookup_smart_contract_address_or_die" still is “{"jsonrpc":"2.0","result":null,"id":1} ” ,I do not know what may be the reason . And I found the "from_address" is different between eth and parity .

The reason is that the smart contract failed to deploy. Can you post your server log?

from blockbench.

The eth_log and client_log as follow:
eth_log.txt

client_192.168.0.128_16.txt

from blockbench.

from the log, it looks like the contract was submitted, but it hasn't been included in a block yet.

try to increase deploy wait time, e.g. specifying "-wt 120" or higher value, in the start-clients.sh

from blockbench.

@xiaohua0921
hello,I am currently experiencing this problem as you said:
driver: evm_utils.cc:334: std::__cxx11::string BBUtils::EVMUtils::lookup_smart_contract_address_or_die(const string&, const string&): Assertionr.find(""result":null") == std::string::npos' failed. " . I found the reason is the code " assert(r.find(""result":null") == std::string::npos); `
How did you solve it at the time? thank you!
