deploy contract always return internal server error

[akbariandev]

I started to test your code. It works only for uploading assets and metadata into IPFS. In the next step, when it wants to deploy a collection contract, the toncenter returns an internal server error. Also I tried to call jsonRpc API from tomceter swagger https://testnet.toncenter.com/api/v2/#/json%20rpc/jsonrpc_handler_jsonRPC_post. But again I got 500 error with below details.

{
  "ok": false,
  "error": "LITE_SERVER_UNKNOWN: cannot apply external message to current state : Failed to unpack account state",
  "code": 500
}

Same problem for me as well.

{ "ok": false, "error": "LITE_SERVER_UNKNOWN: cannot apply external message to current state : Failed to unpack account state", "code": 500 }

@chiliec Your commit, not solving the issue just renaming a variable.

The code crashes on this point

let seqno = await collection.deploy(wallet);

Would be possible to adjust this code, after a collection already minted on the network to just upload new NFTs with code to that collection?

Upload picture/metadata to IPFS. And mint new NFT on the network to existing collection by keeping topUpBalance functions and everything else.

This is because version of wallet you use.
For me, I just change version from WalletContractV4 to WalletContractV3R2 and it worked perfectly

  const wallet = WalletContractV3R2.create({
    workchain: 0,
    publicKey: keyPair.publicKey,
  });

@toannhu96 but it works fine for me even with WalletContractV4. What could be the problem with the newer contract version?

[chiliec]

I have found only one mention of this issue on GitHub, at toncenter/ton-wallet#196, but there is no solution yet.
