help in deploy smart-contract

[xiaohua0921]

When I run the parity and ethereum , I meet the error “ driver: evm_utils.cc:334: std::__cxx11::string BBUtils::EVMUtils::lookup_smart_contract_address_or_die(const string&, const string&): Assertion `r.find(""result":null") == std::string::npos' failed. " . I found the reason is the code " assert(r.find("\"result\":null") == std::string::npos); " in function "lookup_smart_contract_address_or_die" , I have print r，the information is " {"jsonrpc":"2.0","result":null,"id":1} " , but in parity ，the line of code is annotated ，so there haven't this error , so I want to know , whether is correct or not of the r .

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?

[xiaohua0921]

The eth_log and client_log as follow: eth_log.txt

client_192.168.0.128_16.txt

[ug93tad]

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

@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！
