No no no.

The accepted answer above is incorrect, and the fact that you've accepted it means that not many users will even read your question (let alone try to answer it).

The integer value of 1000000000000000000 is indeed larger than Number.MAX_SAFE_INTEGER, and you should therefore use "1000000000000000000" or "1e18". But that's not what the error message tells you, and the suggested solution will therefore not fix that error.

Look at the error:

invalid number value (arg="_amount", coderType="uint256", value={"from":"0xb5Fb3E9BB73e742689F1001C519d6763a39A4Bc5","gas":6721975,"value":1000000000000000000}).

It tells you very explicitly that the function expects a number value (which you can pass as either a native integer Number, a string representing an integer number, a BigNumber object if you're on web3.js v0.x, or a BN object if you're on web3.js v1.x onward), but has received this instead:


Looking at the function that you are trying to call:

function OraclizeTest(uint _amount)

And it indeed expects one input parameter of type uint, which you are no passing to it.

The object which you are passing is an additional parameter which web3.js allows you to pass in order to provide the transaction details. This object must be the last parameter passed to any function, and of course, it is not stated explicitly in the contract function itself (but implicitly via msg).

In short, your call to function OraclizeTest is missing the input parameter _amount.

  • Thank you soo much for the explanation I really needed this.

  • @raghav: You're welcome. Did you understand it all? Jan 13, 2020 at 5:57
  • @raghav: Well, your question implies that you didn't. Did you at least read the bottom line? Jan 13, 2020 at 5:58
  • Actually i understand the fact that i was passing it wrong but now i need to pass the amount from the app.js by taking a user input which i have done but passing it to the constructor is what i am not able to do @goodvibration
