Liquidity.fetchInfo returns not enough error details or returns no data.

[mynote]

IIt seems like that fetchInfo is not returning an error when an account was not found.

  static async fetchInfo({ connection, poolKeys }: LiquidityFetchInfoParams) {
    const info = await this.fetchMultipleInfo({ connection, pools: [poolKeys] })

    logger.assertArgument(info.length === 1, `fetchInfo failed, ${info.length} pools found`, 'poolKeys.id', poolKeys.id)

    return info[0]
  }

Since fetchInfo is just a validator for fetchMultipleInfo and fetchMultipleInfo calls makeSimulatePoolInfoInstruction to create the instructions and forward them mapped to simulateMultipleInstruction.

simulateMultipleInstruction (common/web3.ts) uses simulateTransaction and just returns a "rpc simulateTransaction error".

Its impossible to find the problem since the error itself is not returned.

For example the return value can be:

 [
  {
    "accounts": null,
    "err": "AccountNotFound",
    "innerInstructions": null,
    "logs": [],
    "returnData": null,
    "unitsConsumed": 0
  }
]

which would help alot.

Very often it happens that fetchInfo doesnt return any data and just hang until app restarts.

Also the same check returns very different results. using my testcode it returns RPC_ERROR in about 90% of all requests.

async function getLiquidityTest() {
