Unable to deploy config to Solana network

Question

I'm uploading nft asset to Solana network and got this error.

TypeError: Cannot read properties of undefined (reading 'map')

I'm not sure what to adjust though I've referred to numerous tutorials. Below is the code snippet in upload script of metaplex:

if (i === 0 && !cacheContent.program.uuid) {
        // initialize config
        log.info(`initializing config`);
        try {
          const res = await createConfig(anchorProgram, walletKeyPair, {
            maxNumberOfLines: new BN(totalNFTs),
            symbol: manifest.symbol,
            sellerFeeBasisPoints: manifest.seller_fee_basis_points,
            isMutable: mutable,
            maxSupply: new BN(0),
            retainAuthority: retainAuthority,
            creators: manifest.properties.creators.map(creator => {
              return {
                address: new PublicKey(creator.address),
                verified: true,
                share: creator.share,
              };
            }),
          });
          cacheContent.program.uuid = res.uuid;
          cacheContent.program.config = res.config.toBase58();
          config = res.config;

          log.info(
            `initialized config for a candy machine with publickey: ${res.config.toBase58()}`,
          );

          saveCache(cacheName, env, cacheContent);
        } catch (exx) {
          log.error('Error deploying config to Solana network.', exx);
          throw exx;
        }
      }

And I was uploading the assets through CLI using the following command:

ts-node ~/metaplex-master/js/packages/cli/src/candy-machine-cli.ts upload /nft-assets --env devnet --keypair ~/.config/solana/devnet.json

Answer 1

Check the *.json files in assets folder again. Make sure the creator properties follow correct structure as in https://docs.metaplex.com/nft-standard#json-structure:

{
...
    "creators": [
      {
        "address": "SOLFLR15asd9d21325bsadythp547912501b",
        "share": 100
      }
    ]
}

It is not a plain array of public keys though

Answer 2

This question is missing the backtrace which makes it hard to tell where exactly the problem is.

In my case, I was missing the properties.creators in the metadata. To fix it, verify if you are missing one of the required entries.
