Yarn link works for one file but throws error for another file in same Angular project

Question

I'm trying to build an Angular project where I have 3 files - getComputers.js, getIps.js and one typescript file - app.ts. I need to require a trendmicro module in both Javascript files. For one file it works but for the other it throws a module not found error.

I ran the following line to link the trendmicro module to my project.

yarn link "@trendmicro/deepsecurity"

It gets successfully linked. The problem shows up for getIps.js and doesn't show up for getComputers.js, here is what I tried:

getComputers.js

function getThoseComps(p1,p2)
{
    return new Promise((resolve, reject) => {
         const api = require("@trendmicro/deepsecurity");   //This works
         //...other code
    });
}

getIps.js

function getIPS(p3,p4)
{
    return new Promise((resolve, reject) => {
         const api = require("@trendmicro/deepsecurity");   //This throws error...
         //...other code
    });  
}

app.ts

import { getThoseComps } from "../../assets/js/geComputers.js"
import { getIPS } from "../../assets/js/getIps.js";

@Component({
    selector: 'app-home',
    templateUrl: './home.component.html',
    styleUrls: ['./home.component.scss']
})
export class HomeComponent implements OnInit {

    async fetchComputers() {
        try {
            const obj1 = await getThoseComps(p1,p2); // This works perfect
            const obj2 = await getIPS(p3,p4);     // This causes error...  
        }
        catch(err) {
            console.log(err);
        }
    }

    ngOnInit()
    {
        this.fetchComputers();
    } 
}

Edit:

Note: The error shows up for index.js which according to me is misleading becuase the same error doesn't show up when I require trendmicro module in getComputers.js file. The dsm-js-sdk folder contains that module.
