i'm trying to call this function:

const nonce = web3.eth.getTransactionCount(myAddress) 

On the testnet of this node:


But I get this error on this node:

cannot unmarshal non-string into Go value of type common.Address

at Object.InvalidResponse (.../node_modules/web3/lib/web3/errors.js:35:16)

at RequestManager.send (../node_modules/web3/lib/web3/requestmanager.js:61:22)

at Eth.send [as getTransactionCount] 

Any ideas why this is happening?


Check your variable myAddress. It has to be represented as a hex string, even though it is actually a number. A hex string is a string, starting with 0x. So your definition of myAddress should be something like

const myAddress= "0x....";
