App problem, TEAL level

1

Hi, there!

During an upcoming show, NFT/ASA will be “sold” to the audience, minted right on the spot.

I made a small sample app, along the lines of the TealScript example auction.algo.ts

My first problem was: how to call app ABI method, when there is a PayTxn among the ABI params. This was solved by Ludo @Scholtz, see app call problem, TealScript

So now the test began to run. However, the TEAL code is still not correct:

  • first, it fails with “receiver is not globals.creatorAddress”. But in the test suite the testAccount was used create the app, so it should be the creatorAddress, shouldn’t it?
  • when I comment out this line in the TealScript code, the error reads as “unavailable Asset 1020”. But it IS available, when you check it with DAppflow. asset: 1020 can be seen in the app’s global field asset.
logic eval error: unavailable Asset 1020. Details: app=1016, pc=410, opcodes=bytec_0 // "asset"; app_global_get; itxn_field XferAsset

How can I debug the TEAL code? What tools can be used? What is the method?
If you SEE the error, please write to me. Consider it as a coding challenge.

it would be much better to show the complete code you have…

unavailable Asset 1020 probably means you did not run the bootsrap of the sc, or you did not opt in to the asa

receiver is not globals.creatorAddress probably means you are calling the buyAsset method instead calling some bootrsap method… i assume you should call buyAsset when you want to close the auction and send to the creator the auctioned usdc for example. In your code you dont show where u create application, and if it was supposed to be by testAccount.addr you perhaps have to tell the client that the original sender is testAccount

Hi, Ludo @scholtz ,
The code is here: biz_kor
It is a tiny-tiny app – my first app (after @joe-p ).I committed it at 20:50 CET.
Thanks for your caring.

P.S. I DID run bootstrap, and got an asset id of 1020. The asset is created withon the app.
It is more simple than an auction: just a demo of tokenized RWA. So anybody can “buy” the
NFT/ASA created in the smart contract.

unavailable Asset 1020 means it’s not in the transaction as an available resource. AVM must know all state that is accessed before execution. A the simplest way to address this is to enable resource population.

You can see an example of this here TEALScript/examples/tuple_in_box/client.ts at d8d4f78384f07fb497d3bb065a488ddd33fba869 · algorandfoundation/TEALScript · GitHub

You mean algokit.Config.configure({ populateAppCallResources: true });?
It was already in the test.

What version of algokit-utils are you on?

$ cat package.json
  "dependencies": {
    "@algorandfoundation/algokit-utils": "^5.5.0",
.

.
$ algokit --version
algokit, version 2.0.1

From the test run I see:

  • testAccount is used to create the app.
  • app checks if Algo is sent to creator – but when is does the check, the test_account (the supposed creator) is already changed by const { algod, testAccount } = fixture.context; and money is sent to that address, and the app fails.

So now, I allocate an account from KMD to buy the NFT, and another account to create the app. Now my TEAL assertations don’t fail at once. But I get the same error: logic eval error: unavailable Asset 1079. Details: app=1075, pc=438, opcodes=bytec_0 // "asset"; app_global_get; itxn_field XferAsset

@joe-p As my app is a “variation” on @joe-p Tealscript DOA example (proposal, voting), it would help a lot, if you could give me the repository, where this example is.

The challenge is still not solved: “unavailable asset”. See the source. Any guesses, suggestions, or solutions?

Your can easily try it in codespaces, just like the other, “more convenient” Algorand coding challenges.

Thanks for your help,
Maugli

i think your issue is that you should write tests without dependency on other tests…

you do not run the bootstrap in this test (nor in the before each test section) : akt02/biz_kor/projects/biz_kor-contracts/__test__/BizKor.test.ts at e0f732d34166df88b0d9c3f1f7f508664a7cd4b0 · A-Maugli/akt02 · GitHub

Dear Ludo @scholtz , you are right. In the meantime I changed the tests, and now a fixed, allocated account is used to create the app. But the problem still prevails.

There is no “unavailable asset” error during the buyAsset method, when in the app call the asset id is also passed in the assets array:

    const compose = appClient.compose().buyAsset(
      {
        payment: tx1,
      },
      {
        sender: signer1,
        sendParams: {
          fee: algokit.microAlgos(3000),
        },
        assets: [Number(asset)],
      }
    );

    const atc = await compose.atc();
    const txs = atc.buildGroup().map((tx) => tx.txn);

Thank you for help and for your example, @scholtz
