Subgraph not deploying

[harendra-shakya]

I'm trying to deploy my subgraph and I'm getting this error.

✖ Failed to deploy to Graph node https://api.studio.thegraph.com/deploy/: subgraph resolve error: resolve error: Serialization error: missing field `name` at line 216 column 3

Can someone explain me what does this error mean and how to resolve it.

this is my 216 line on generated/schema.ts

line 215                         get nftAddress(): Bytes {
line 216                              let value = this.get("nftAddress");
line 217                              return value!.toBytes();
                            }

And Nftmarketplace abi under build folder has name getProceeds near line 216. What's wrong?

Everything is auto generated like schema or build folder so they can't be wrong. I have tried deleting and doing everything 2-3 times. But it's not working. What am I missing? @PatrickAlphaC

I have solved the error. I was using old version yarn so I upgraded it and at the same time I also created a new graph with a new account and it worked.

i met the similar issue, and can't solve it in you way, confusing

Just giving an update in case someone runs into this issue. I had a similar error:

Serialization error: missing field `name` at line 241 column 3

Looking into the ABI of the contract (that had been thrown into the build folder), line 241 would be the beginning of the getProceeds function. Here is it:

{
    "type": "function",
    "name": "getProceeds",
    "constant": true,
    "stateMutability": "view",
    "payable": false,
    "gas": 29000000,
    "inputs": [
      {
        "type": "address",
        "name": "user"
      }
    ],
    "outputs": [
      {
        "type": "uint256"
      }
    ]
  }

Which outputs a uint256, but with no name. It's due to the way I had written the function in the contract:

function getProceeds(address user)
        external
        view
        returns (uint256)
    {
        return s_proceeds[user];
    }

So I just added uint256 proceeds as the return value, which compiled into the ABI adds that missing name field.

And now deploying with TheGraph works!

Hi @polar0 ,

Many thanks for your info. I ran into the exact same issue with this function and fixed it with your solution.

Unfortunately, I still get the this error in another line when I ran the deploy command.
I've double checked the functions in my contract, there's no name field missing.

Would you please take a look at my query here and see if you can find anything? Thanks in advance.
