ConseilJS TezosContractIntrospector.generateEntryPointsFromAddress `Uncaught (in promise) TypeError: Cannot read property '0' of undefined`

Question

Trying to retrieve contract entry points using the TezosContractIntrospector

The following code:

async function entry_points(){
  const server={
    url:'https://conseil-dev.cryptonomic-infra.tech:443',
    apiKey:'foo',
    network:'babylonnet
  };
  const contractAddress='KT1WRUe3csC1jiThN9KUtaji2bd412upfn1E';
  const result=await conseiljs.TezosContractIntrospector.generateEntryPointsFromAddress(
    server,
    server['network'],
    contractAddress
  );
}

attempts to interact with the deployed contract from a medium post but results in the error:

conseiljs.min.js:2 Uncaught (in promise) TypeError: Cannot read property '0' of undefined
  at Object.<anonymous> (conseiljs.min.js:2)
  at Generator.next (<anonymous>)
  at o (conseiljs.min.js:2)

If typeof is used:

console.log(typeof(
  conseiljs.TezosContractIntrospector.generateEntryPointsFromAddress(
    server,
    server['network'],
    contractAddress
  )
);

it is of type object but I am unsure how to handle it.

I wish to find the entry points of a contract to use it to sendContractInvocationOperation

Any help is much appreciated

Answer 1

The function preprocesses input and eventually passes to generateEntryPointsFromParams

Due to the issues encountered with generateEntryPointsFromAddress I used the following workaround:

async function foo(contract_params){
  const entry_points=await 
    conseiljs.TezosContractIntrospector.generateEntryPointsFromParams(contract_params);
  console.table(entry_points);
}

This will display the entry points. Which is the desired results.

Parameters can usually be easily retrieved (for example, from an online explorer).
