Hey devs what could be reason of this error when interacting with smart contract?
Cannot read properties of undefined (reading ‘match’)

I’m trying to interact with SC when i invoke the function it returns only this error

here is my function

// SMART CONTRACT  CREATE POST
        const createNewPost  =  async ()  =>  {
           // awaitsavePostData()
           let options = {
              contractAddress : "0x60Ae865ee4C725cd04353b5AAb364553f56ceF82",
               abi : LENS_HUB,
                params : {
                vars: {
                  profileId: "0x41cd",
                  contentURI: 'https://ipfs.io/ipfs/Qmby8QocUU2sPZL46rZeMctAuF5nrCc7eR1PPkooCztWPz',
                  collectModule: "0xaeB7E3326e4745639574092801ad5C4467d513c9",
                  collectModuleInitData: "0x0000000000000000000000000000000000000000000000000000000000000001", //defaultAbiCoder.encode(['bool'], [true]),
                  referenceModule: "0x0000000000000000000000000000000000000000",//ZERO_ADDRESS,
                  referenceModuleInitData: [],
                }
               }
            }
          contractExcutor.fetch({
            params: options,

            onSuccess : () => {
              console.log("the post  have  been created  succesfully")
            },

            onError: (error) => {
              console.log(error.message)
            }
          })

        }

I have no idea what I’m doing wrong here ?

Need more details from which script you are getting this error.

And also check if the function name and other values added to the params are not undefined.

#3

the function I’m trying to interact with it has only 5 parameters
1- profileId 2 contentURI, collectModule, collectModuleInitData, referenceModule and referenceModuleData

here is function ABI

  {
       "inputs":[
          {
             "components":[
                {
                   "internalType":"uint256",
                   "name":"profileId",
                   "type":"uint256"
                },
                {
                   "internalType":"string",
                   "name":"contentURI",
                   "type":"string"
                },
                {
                   "internalType":"address",
                   "name":"collectModule",
                   "type":"address"
                },
                {
                   "internalType":"bytes",
                   "name":"collectModuleInitData",
                   "type":"bytes"
                },
                {
                   "internalType":"address",
                   "name":"referenceModule",
                   "type":"address"
                },
                {
                   "internalType":"bytes",
                   "name":"referenceModuleInitData",
                   "type":"bytes"
                }
             ],
             "internalType":"struct DataTypes.PostData",
             "name":"vars",
             "type":"tuple"
          }
       ],
       "name":"post",
       "outputs":[
          {
             "internalType":"uint256",
             "name":"",
             "type":"uint256"
          }
       ],
       "stateMutability":"nonpayable",
       "type":"function"
    },

#4

all params are defined

#5

You did not add the function name in options. It is missing.

this solved first problem but i still i get another error Cannot read properties of undefined (reading ‘length’)

#7

where from is that error with length?

#8

I think this was because I forgot to use await when i added this is not returning … length anymore now it throws network does not support ENS (operation=“getResolver”, network=“maticmum”, code=UNSUPPORTED_OPERATION, version=providers/5.6.0)

any clue on how to solve this .

#9

what is this network?

#10

is mumbai testenet network

#11

Solved in profileId was a white space " ID" instead of “ID”

and the error of Cannot read properties of undefined (reading ‘length’) I have no i dea where it cames from tried to double check params but not found anything see my function code here :point_down:

 async function createNewPost ()  {
         let options = {
          contractAddress : "0x60Ae865ee4C725cd04353b5AAb364553f56ceF82",
          functionName : "post",
          abi : LENS_HUB,
          params: {
            vars : {
              profileId: "0x41cd",
             collectModule : "0x0BE6bD7092ee83D44a6eC1D949626FeE48caB30c",
             collectModuleData: defaultAbiCoder.encode(['bool'], [true]),
              referenceModule: ZERO_ADDRESS,
              referenceModuleData: [],
            }
          }
         }

         await contractExcutor.fetch({
          params: options,
          onSuccess : () => {
            console.log("the post  have  been created  succesfully")
          },

          onError: (error) => {
            console.log(error.message)
          }
         }) 
      }

All parameters i followed this documentation :point_right: Smart contract documentation

what is the abi? can you pun only the abi specific to that function?

#13

here is function ABI

       "inputs":[
          {

#14

this seems like a complex abi, you could try to edit the abi and remove that tuple so that it is a simple abi

#15

Im also facing same issue here is code

          address: DogAdress,
          function_name: 'createCollectible',
          abi: Abi,
          Params: {_tokenURI: url },
        };
        // const price = ethers.utils.parseUnits(formInput.price, 'ether')
        const mint =await Moralis.executeFunction(options)
        console.log(mint)
        await mint.wait()
thats my abi 
```const Abi=  {
          "inputs": [
            {
              "internalType": "string",
              "name": "_tokenURI",
              "type": "string"
            }
          ],
          "name": "createCollectible",
          "outputs": [
            {
              "internalType": "uint256",
              "name": "",
              "type": "uint256"
            }
          ],
          "stateMutability": "nonpayable",
          "type": "function"
        }
#16

You should have your abi as such rather

[
  {
    "inputs": [
      {
        "internalType": "string",
        "name": "_tokenURI",
        "type": "string"
      }
    ],
    "name": "createCollectible",
    "outputs": [
      {
        "internalType": "uint256",
        "name": "",
        "type": "uint256"
      }
    ],
    "stateMutability": "nonpayable",
    "type": "function"
  }
]
#17

ok also Ive a question can we call contract function that require signer to sign a transaction but I dont why this method isnt working with wallet connect in mobile

#18

this function need signer and still getting the same error

#19

What is the error? Does it work in browser with MetaMask?

#20

no jani Im posting whole code

        // const Market = new ethers.Contract(marketplaceAddress, Marketplace.abi, library.getSigner())
        // const Dog = new ethers.Contract(
        //   DogAdress,
        //   NFTDog.abi,
        //   library.getSigner()
        // );
        // // const price = ethers.utils.parseUnits(formInput.price, 'ether')
        // const collectible = await Dog.createCollectible(url);
        const Abi=[
          {
            "inputs": [
              {

                "name": "_tokenURI",
                "type": "string"
              }
            ],
            "name": "createCollectible",
            "outputs": [
              {

            "stateMutability": "nonpayable",
            "type": "function"
          }
        ]

        const options={
        
        address: DogAdress,
        function_name: 'createCollectible',
        abi: Abi,
        Params: {_tokenURI: url },
