[Bug]: Can't mint because of the "0x7dc" error

[merlox]

Which package is this bug report for?

candy machine ui

Issue description

1. Deploy the cli candy machine to the testnet with this config:

   {
   "price": 0.01,
   "number": 7,
   "gatekeeper": {
       "gatekeeperNetwork" : "ignREusXmGrscGNUesoU9mxfds9AiYTezUKex2PsZV6",
       "expireOnUse" : true
   },
   "solTreasuryAccount": "6z9nhc3VzRJ2UwFZqbgu6ZxRtmnBc32JvSFtizvcFZrU",
   "splTokenAccount": null,
   "splToken": null,
   "goLiveDate": 1646583165849,
   "endSettings": {
       "endSettingType": { "amount":true },
       "value": 7
   },
   "whitelistMintSettings": null,
   "hiddenSettings": null,
   "storage": "nft-storage",
   "ipfsInfuraProjectId": null,
   "ipfsInfuraSecret": null,
   "nftStorageKey": "(I'm using a real API key here)",
   "arweaveJwk": null,
   "awsS3Bucket": null,
   "noRetainAuthority": false,
   "noMutable": false 
   }

2. After a successful upload to testnet I start the candy machine UI by updating the .env file with the right candy machine deployed program ID.
3. I tried to mint and everytime I get this error:

   Signed txns length 1 vs handed in length 2
   connection.tsx:366 Started awaiting confirmation for 3RzvVoWm4c4KGq9W3uq47QJd5ESy4t8VFfoprLHNRcsmic5z6E3Y4ZoFDcGmEDi5Cat8UoWf5wDnpyacGuqJH47m

   candy-machine.ts:535 Error: Transaction failed: Custom program error: 0x7dc
   at sendSignedTransaction (connection.tsx:411:1)

Command

ts-node js/packages/cli/src/candy-machine-v2-cli.ts upload -e testnet -k /Users/merunas/.config/solana/devnet.json -cp ./upload.json -c solarbears ./upload-files

Then inside candy-machine-ui I do:

yarn start

Relevant log output

Priority this issue should have

Medium (should be fixed soon)

Check the Docs First

I execute the mint but the transaction in phantom always fails. Not sure why, have you guys tried to run it in testnet?

[merlox]

It looks like a CLI error. Can someone explain what that 0x7dc means?

Our programs aren't deployed on testnet. Try using mainnet-beta or devnet, although the latest solana devnet release is like basically broken and nothing is working for our programs :/

[merlox]

can you deploy them to testnet or tell me which ones are so I can deploy them there? testnet works so good right now compared to dev net

[merlox]

sounds like a pretty big deal that you can't run the app without deploying to mainnet. We should be able to run in all test networks AND localhost.
