Ethereum nodejs Unhandled rejection Error Invalid JSON RPC response

Question

Is there something wrong with my command?

contract.methods.thu().send(
   { from: senderAddress, 
     gasPrice: web3.utils.toHex(GAS_PRICE), 
     gasLimit: web3.utils.toHex(GAS_LIMIT)
   }
);

When I execute it, I get this error:

Unhandled rejection Error: Invalid JSON RPC response: ""

Need to help

Answer 1

gasLimit is actually represented by gas as the gas limiter according to the docs: http://web3js.readthedocs.io/en/1.0/web3-eth-contract.html#methods-mymethod-send

contract.methods.thu().send(
   { from: senderAddress, 
     gasPrice: web3.utils.toHex(GAS_PRICE), 
     gas: web3.utils.toHex(GAS_LIMIT)
   }
)

Also, it's probably best to use the parameter types of gasPrice (String) and gas (Number) from the docs.
