I'm trying out the eosjs official documentation, but can't make any RPC calls. This is how I've initialized everything:

const { Api, JsonRpc, RpcError } = require('eosjs');
const { fetch } = require('node-fetch');
const rpc = new JsonRpc('http://jungle2.cryptolions.io:80', { fetch });


I get an error saying:

{ TypeError: f is not a function
    at JsonRpc.<anonymous> (/home/krtk6160/Desktop/konnectSense/node_modules/eosjs/dist/eosjs-jsonrpc.js:99:46)
    at step (/home/krtk6160/Desktop/konnectSense/node_modules/eosjs/dist/eosjs-jsonrpc.js:36:23)
    at Object.next (/home/krtk6160/Desktop/konnectSense/node_modules/eosjs/dist/eosjs-jsonrpc.js:17:53)

    at JsonRpc.fetch (/home/krtk6160/Desktop/konnectSense/node_modules/eosjs/dist/eosjs-jsonrpc.js:92:16)
    at JsonRpc.<anonymous> (/home/krtk6160/Desktop/konnectSense/node_modules/eosjs/dist/eosjs-jsonrpc.js:208:55)
    at step (/home/krtk6160/Desktop/konnectSense/node_modules/eosjs/dist/eosjs-jsonrpc.js:36:23)
    at Object.next (/home/krtk6160/Desktop/konnectSense/node_modules/eosjs/dist/eosjs-jsonrpc.js:17:53) isFetchError: true }

I've tried with eosjs versions 20.0.0, 20.0.0beta3, 20.0.0beta1 but the error is the same.


The problem was how I was importing the fetch module. I was able to fix the issue by importing the fetch module in the following way:

const fetch = require('fetch')
