Lesson 15 failed when deploying subgraph

[cckoyou]

when i execute the command graph deploy --studio nft-marketplace, error is as below:
Failed to deploy to Graph node https://api.studio.thegraph.com/deploy/: subgraph resolve error: resolve error: Serialization error: missing field 'name' at line 70 column 3
it doesn't show exactly which file the error comes from. I also checked the forum of thegraph and didn't find the related topic. Did anyone meet the same issue?

Could you push to GitHub? I will look into it

kindly help, thanks!

src/nft-marketplace is incomplete, hence the error.

I will make a PR with my own code, only merge it if you have finished the lesson. If not, follow along with Patrick.

i don't think that's the root cause, here is what i've tyied:

1. delete all the files in folder graph-nft-marketplace-fcc
2. execute graph init --studio nft-marketplace
3. didn't change any code of new generated files
4. execute the next commands including deploy
   the result turned out exactly the same, even indicated the same line(line 70 column 3).

there is another similar query #485, and i followed in the same way but it din't work.

anyway, i give up for now and move on to the next part of video.

I'm copy/pasting this solution I found and gave in another post, in case someone comes here.

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!
