unable to upload nfts using metaplex

Question

while am uploading Nft asset to Solana network and have this error :

 Beginning the upload for 22 (img+json) pairs
started at: 1646166389888
initializing candy machine
Error deploying config to Solana network. Error: Invalid config, there must be a symbol.

I was uploading the assets through CLI using this command:

ts-node metaplex/js/packages/cli/src/candy-machine-v2-cli.ts upload  -e devnet -k 
config/solana/devnet.json  -cp config.json  metaplex/assets

Most of the guides on the web would recommend having symbol: "" but the latest update in Metaplex Candy Machine (0.0.2) actually expects non-empty value here for your NFT's JSON files.

So the fix is simply updating the symbol field to have some value in it, e.g. symbol: "TEST_NFT",

The full explanation is here

Using metaplex-0.0.2 I could mint nft's with symbol:""

Looks like you dont have have correct config for the nft asset.

{
  "name": "name",
  "symbol": "",
  "image": "2.png",
  "properties": {
    "files": [
      {
        "url": "2.png",
        "type": "image/png"
      }
    ],
    "creators": [
      {
        "address": "21J9Vk6pX34pPW18gLxGj5Am6czmeKC6CEtQChztAuKY",
        "share": 100
      }
    ]
  }
}

You Can try with command like this

ts-node C:/Users/aditya/Desktop/PracticeCodes/NftMinting/~/deprecated-clis/src/candy-machine-v2-cli.
ts upload \ -e devnet \ -k payer.json \ -cp config.json \  ./assets

Please try to elaborate on what those commands are doing and how they function to solve the problem. – Slight Feb 26 '23 at 16:58
