How to pass bytes parameter to contract method call using Web3.js?

Question

I'm trying to call a method in a contract and the method is like this:

function myMethod(uint8 tid, bytes calldata _bytes)
    public
    view
    returns (string memory)
{ ... }

I'm using Web3.js to call the methods and I have done successful ones on other methods but I can't find a way to pass bytes data to call this method. I would appreciate it if you could help me.

Answer 1

bytes is a variable type that holds a sequence of bytes from 1 to up to 32.

Read about it in the docs.

On Web3 you use numberToHex or utf8ToHex for strings.
