"No matching function" in the ABI

See original GitHub issue

I’m having a similar issue. Using V5 under NodeJS

const fillInterface = new ethers.utils.Interface(FILL_ORDER_ABI);        // function abi
const data =  fillInterface.encodeFunctionData("fillOrder",[orderTuple, takerAssetFillAmount, signature])

Error: no matching function (argument=“name”, value=“fillOrder”, code=INVALID_ARGUMENT, version=abi/5.0.9)

The ABI

                        }

Not sure why it wont see the function. This ABI was working with WEB3

Can you show more of your code? This works for me:

const { ethers } = require("../../packages/ethers");

const abi = [
    {
                           "constant":false,"inputs":[

                                   {"internalType":"address","name":"feeRecipientAddress","type":"address"},

Based on the “thumbs up”, I’m guessing your issue is resolved? 😃

I’m going to close this now, but if you have any further issues, please re-open.

Thanks! 😃

Nope but I was sure it was. Not sure if something is wrong with my abi. Interface is looking for an array given the map error.
