getting this error could this be because the solana chain is congested?

hey guys @great9 @orao-dev1 do you know which projects are currently using this SDK? or any examples/visual tutorials I can see? thanks in advance!

When I import js library via npm in my nextjs app, I got an error.

./node_modules/@orao-network/solana-vrf/dist/index.js:18:0
Module not found: Can't resolve 'tweetnacl'

` const vrf = new Orao(provider);

let force = Buffer.from(Keypair.generate().publicKey.toBuffer());
const [seed, tx] = await (await vrf.request(force)).rpc()

const randomness = await vrf.waitFulfilled(force);
console.log("Your randomness is " + randomness.fulfilled());`

I tried to get random number but the error says
Error: Account does not exist or has no data

So, I tried to change the commitment of vrf.waitFulfilled(force); to confirmed but it doesn't respond for hours.

Hi!

I deployed the program to my own program_id,
but when I'm trying to play using the CLI I'm getting an Error,
state command is working well.
how to solve it?
Thanks.

Command:
cargo run -q --package roulette-cli -- play

Output:

Loading a bullet and spinning the cylinder..
Error: RPC response error -32002: Transaction simulation failed: Error processing Instruction 0: custom program error: 0x1004 [4 log messages]
Caused by:

Expected Output:

Loading a bullet and spinning the cylinder..
Waiting for the round to finish..
CLICK! Player <MY_PUBLIC_KEY> is alive after 1 round(s)

Command:
cargo run -q --package roulette-cli -- state

Output == Expected Output:

Version: orao-network/solana-vrf 0.2.1

The orao vrf documentation states that randomAcc.fulfilled() returns the randomness if fulfilled
`
var randomAcc = undefined;

    try {
      randomAcc = await vrf.getRandomness(gen_seed.publicKey.toBytes());
      console.log(randomAcc);

    } catch (err) {
      toast.notify(`${err.message}`, { type: "error" });

    }
  
  var randomness = randomAcc.fulfilled();

  if (randomness === null) {
    console.log("Randomness is not yet fulfilled " + i);
  } else {
    console.log("Randomness is " + randomness);
    return;
  }`

i keep receiving the following error indicating the 'fulfilled()' function. Error says TypeError: Argument must be a Buffer

I mention that when executing tests on the anchor env it works. But in this case i have a nextjs + react app

The program works fine on local host but as soon as I switch to Devnet the tests fail.

I’ve spent hours looking through the code to find a solution but my only guess is that it’s something to do with the before block in the tests file.

Have you got any ideas on how to fix this?

ZKVerse is one of our latest client using out vrf on solana. We've made some bts upgrades to lower the randomness fulfillment time.

Hi , when I request for randomness , this error Error: Account does not exist <"some address"> after fee debit from my account.

Please help , as this is happening on mainnet
