Getting contract entries with js-soroban-client

[ocean pumice]

I'm trying to get contract entries by keys from ledger and got stuck at the very first step.
At the docs https://github.com/stellar/js-soroban-client/blob/main/docs/reference/readme.md#xdr I see:

new SorobanClient.xdr.LedgerKeyAccount({
    accountId: 'GASOCNHNNLYFNMDJYQ3XFMI7BYHIOCFW3GJEOWRPEGK2TDPGTG2E5EDW'
  })

It doesn't work, and I can get accountId only from keyPair.xdrAccountId(). keyPair may be got from user address with SorobanClient.Keypair.fromPublicKey('...'). But it doesn't work with smart contract public key.

And then I should probably use something different from xdr.LedgerKeyAccount.

it might be easier with getContractData
https://github.com/stellar/js-soroban-client/blob/684f1b352d944743ffdf4e151cba8216a742ecf0/src/server.ts#L174

Thank you, I tried but it returns 404 anyway.
I also tried getLedgerEntries but even comment docs are obsolete.

not sure what you are trying to get.
Have you checked this?
https://github.com/stellar/js-soroban-client/blob/684f1b352d944743ffdf4e151cba8216a742ecf0/src/server.ts#L96

    const ledgerKey = xdr.LedgerKey.account(
      new xdr.LedgerKeyAccount({
        accountId: xdr.PublicKey.publicKeyTypeEd25519(
          StrKey.decodeEd25519PublicKey(address),
        ),
      }),
    ).toXDR("base64");

404 usually means the resource does not exist, either the account or the contract (may be expired?)

[ocean pumice]

Yes, the contract actually expired today, but we redeployed it. I can see our token balance in Frighter.

Yes, I tried server.getAccount recently, but it's about accounts, not smart contracts as I see.

I'm trying to get a smart contract entity value by a key, but none of them work.

I also want to get our custom token balance but I don't get how to at the moment.

if you have the contract and its wasm, you could generate the binding code. This code includes (de)serialization functions for the contract types.

you could use that to query the ledgerEntries

[ocean pumice]

Yep, we've generated contract bindings and I can see keys there but I have no clue where queries are.

I made it with getLedgerEntries:

const ledgerKey = SorobanClient.xdr.LedgerKey.contractData(
    new SorobanClient.xdr.LedgerKeyContractData({
      bodyType: SorobanClient.xdr.ContractEntryBodyType.dataEntry(),
      contract: new SorobanClient.Contract(CONTRACT_ADDRESS).address().toScAddress(),
      durability: SorobanClient.xdr.ContractDataDurability.persistent(),
      key: SorobanClient.xdr.ScVal.scvSymbol('counter'),
    }),
  )
  server.getLedgerEntries([ledgerKey]).then((response) => {
    const ledgerData = response.entries?.[0]
    if (ledgerData) {
      console.log('key:', ledgerData.key)
      console.log('value:', ledgerData.xdr)
      console.log('lastModified:', ledgerData.lastModifiedLedgerSeq)
    }
    console.log('latestLedger:', response.latestLedger)
  })

It returns only response.latestLedger.

Finally I got some xdr with a correct RPC server and persistent values, because key doesn't return instance values.

Now I'm trying to parse getLedgerEntries returned xdr with no luck.
