Project 9 Token Lottery - TypeError: Cannot read properties of null (reading 'account')

[freddyal0x01]

Whenever I run anchor --skip-local-validator I get this the following error:

    TypeError: Cannot read properties of null (reading 'account')

I am on the following dependencies for switchboard:

• Cargo package: switchboard-on-demand = "0.3.5"
• NPM package: "@switchboard-xyz/on-demand": "^1.2.66",

[kuchaguangjie]

try to change the api key to yours, in the .ts file.

[freddyal0x01]

Change the API key? There is no API key to change.

[kuchaguangjie]

check this line:

developer-bootcamp-2024/project-9-token-lottery/tests/token-lottery.ts

Line 25 in c65782b

{connection: new anchor.web3.Connection("https://mainnet.helius-rpc.com/?api-key=792d0c03-a2b0-469e-b4ad-1c3f2308158c")}

[freddyal0x01]

I'm not using that code, for some reason running before as a function like that doesn't work for me at all.

I have it like this:

  beforeAll(async () => {
    const switchboardIDL = (await anchor.Program.fetchIdl(
      sb.ON_DEMAND_MAINNET_PID,
      {
        connection: new anchor.web3.Connection(
          "https://mainnet.helius-rpc.com/?api-key=fd78363d-a5ae-4dc4-bb58-7fd46ed790ba",
        ),
      },
    )) as anchor.Idl;

    switchboardProgram = new anchor.Program(switchboardIDL, provider);
  });

I use my own API mainnet key from Helius.

[kuchaguangjie]

Have you figured out the steps to run the project? There is a setup/ dir, I'm not sure how to use that, and the readme is almost useless, it only has a link to a video of 2.5 hours, too long to watch. So, it seems before run anchor test need to run some setup ..

[kuchaguangjie]

I created a queue of switchboard, and replaced its address in the .ts tests, and switched to devnet, it still says the queue is not found ..

[freddyal0x01]

In the setup dir, you simply run a couple of a bash scripts. You first run local-setup.sh and then run the start sh file. Next you do anchor test --skip-local-validator.

[kuchaguangjie]

Thx, which network to run on, devnet or localnet or need mainnet ?

[kuchaguangjie]

Running localnet for the test, I see your error.
Fixed via:

  before("Loading switchboard program", async () => {
    const switchboardIDL = await anchor.Program.fetchIdl(
      sb.ON_DEMAND_DEVNET_PID,
      { connection: new anchor.web3.Connection("https://devnet.helius-rpc.com/?api-key=" + apiKey) }
    );
    switchboardProgram = new anchor.Program(switchboardIDL, provider);
  });

or

  before("Loading switchboard program", async () => {
    const switchboardIDL = await anchor.Program.fetchIdl(
      sb.ON_DEMAND_MAINNET_PID,
      { connection: new anchor.web3.Connection("https://mainnet.helius-rpc.com/?api-key=" + apiKey) }
    );
    switchboardProgram = new anchor.Program(switchboardIDL, provider);
  });

Now the error become Queue account not found.

[freddyal0x01]

So change it to devnet and the problem is solved? How did you import the before function? Where does the before function come from? I have to change it to before all o had import issues with before.

[kuchaguangjie]

The Queue account not found is due to my Anchor.toml use devnet, I changed to use localnet then the error is gone.
Now need to remove the part [[test.validator.clone]] in Anchor.toml, now Anchor.toml looks like this:

[toolchain]

[features]
resolution = true
skip-lint = false

[programs.Localnet]
token_lottery = "DAkoXJUoFaDS5XuTNCqGcnW9y395aMpA3taJwC9rnRgo"

[registry]
url = "https://api.apr.dev"

[provider]
cluster = "Localnet"
# cluster = "Devnet"
wallet = "~/.config/solana/id.json"

[scripts]
test = "pnpm ts-mocha -b --import=tsx -p ./tsconfig.json -t 1000000 tests/**/*.ts"

[test]
startup_wait = 5000
shutdown_wait = 2000
upgradeable = false

# [[test.validator.clone]]
# address = "metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s"

And the 2 tests passed 2 tests fail now:

  2 passing (4s)
  2 failing

  1) token-lottery
       Is committing and revealing a winner:
     TypeError: Cannot read properties of null (reading 'account')

[kuchaguangjie]

So change it to devnet and the problem is solved? How did you import the before function? Where does the before function come from? I have to change it to before all o had import issues with before.

The before function is from the original source code. You need to run pnpm i or yarn i before run tests depends on which cmd is used in Anchor.toml.

In .ts file, I'm using this now:

  before("Loading switchboard program", async () => {
    const switchboardIDL = await anchor.Program.fetchIdl(
      sb.ON_DEMAND_MAINNET_PID,
      { connection: new anchor.web3.Connection("https://mainnet.helius-rpc.com/?api-key=" + apiKey) }
    );
    switchboardProgram = new anchor.Program(switchboardIDL, provider);
  });

It just call the helius api to get the switchboard idl.

You need replace the apiKey variable in the above code with your own helius api key, which is free, you need to login and get it.

[kuchaguangjie]

Now the error is at this line:

const sbCommitIx = await randomness.commitIx(queue);

Error msg:

  1) token-lottery
       Is committing and revealing a winner:
     TypeError: Cannot read properties of null (reading 'account')

[kuchaguangjie]

The above error is fixed by this answer: https://solana.stackexchange.com/a/20878/6642

Though then another new error pop up.
