I am using 'web3.eth.sign` to sign a message, using following code snippet:

web3.eth.sign(msgHash, address, async (err, signedMsg) => {
  if(err) {
    console.log(err)
    resolve(false)
  } else {
    let { r,s,v } = await getRSV(signedMsg)
    resolve({ r,s,v })
  }

Where:

address: 0x7b9f2B209A6CeF0525e49aE1409a21F3E6f33E6B
masgHash: 0x1df7d7e71ce2983d96a3579b72721945407e0b6887dfb20cc5d9dac03352e765

But this giver error

Node error: {"code":-32602,"message":"invalid argument 0: hex string has length 64, want 40 for common.Address"}

Looks like you're on web3.js v0.x, where the order of the first two arguments to this function is opposite to that of web3.js v1.x:

  • Thanks. I am using web3@1.0.0-beta.48, so I was doing it right. I can verify that as when I switch the params, I get error: ` Error: Provided address "0x1df7d7e71ce2983d96a3579b72721945407e0b6887dfb20cc5d9dac03352e765" is invalid, the capitalization checksum test failed` – Prashant Prabhakar Singh Mar 10 '19 at 20:22
  • @PrashantPrabhakarSingh: You might want to try v37 or lower. I'm pretty sure that there are various problems in later versions (I'm personally staying at 34 for now). – goodvibration Mar 10 '19 at 20:25
  • Thanks for recommendation. Will switch to 34 :) – Prashant Prabhakar Singh Mar 10 '19 at 20:26
  • @PrashantPrabhakarSingh: With regards to your actual problem - have you made sure to use strings (and not numbers, since those would be too large for JS)? – goodvibration Mar 10 '19 at 20:26

    Downgrading to v 34 resolved the issue. Thanks :) – Prashant Prabhakar Singh Mar 10 '19 at 20:44
