Loading image location from JSON file dynamically - (Cannot find module...) React, Next.js

Question

I'm trying to dynamically load information from this JSON file and plug it into a component.

{
    "team": [
        {
            "id": "",
            "name": "",
            "role": "",
            "bio": "",
            "major": "",
            "image": "akh.jpg"
        },
       {
            "id": "",
            "name": "",
            "role": "",
            "bio": "",
            "major": "",
            "image": "chr.jpg"
        }
    ]
}

The location of my code is /pages/about/index.js and my JSON file is in /pages/about/about.json.

They way I'm parsing the code is like this:

var data = require('./about.json')
var teams = data['team'];

<ul>
   {teams.map((person) => {
      var basePath = "/public/images/profiles/";
      var loc = require(basePath + person.image);
      return <ProfileCard key={person.id} id={person.id} name={person.name} role={person.role} major={person.major} image={loc} />
   })}
</ul>

The component is located in the same file. I'm only attaching the img element from the profile since the rest work fine.

<img className="" src={require(props.image)}></img>

If I take out the img element or put in an actual path, it works perfectly but this way isn't working. The only similar post I could find was this one, but it never got an answer. StackOverflow: importing image dynamically (React Js) (Require img path cannot find module)

Updated Code 1:

<ul>
  {teams.map((person) => {
    var basePath = "/public/images/profiles/";
    return <ProfileCard 
       key={person.id} 
       id={person.id} 
       name={person.name} r
       role={person.role} 
       major={person.major} 
       image={`${basePath}/${person.image}`} />
   })}
</ul>

And the component is now like this after removing require().

<img src={props.image}></img>

Updated Code 2: Switched to next/image from img and it works! I had to remove the last / and it worked.

In NextJS images are served from / (root), so you shouldn't have to use public in your path, or use require for that matter. Just generate a standard string. It should be as simple as...

import aboutJson from './about.json'

const teams = aboutJson[teams]

const basePath = '/images/profiles/'

const Teams = () => (
   <ul>
      {teams.map((person) => <ProfileCard 
         key={person.id} 
         id={person.id} 
         name={person.name} 
         role={person.role} 
         major={person.major} 
         image={`${basePath}/${person.image}`} 
       />
   )}
   </ul>
)

const ProfileCard = ({ image, ...props }) => <img src={image} />

Also, next does provide its own image component:

import Image from 'next/image'

const ProfileCard = ({ image, ...props }) => <Image src={image} />

This may be the sign of an underlying issue because when I remove the require, the images don't load at all. I get the "image not found" square symbol. – Akhil Sukhthankar Dec 18 '20 at 19:56
Can you post your updated code? Also, I updated my example to remove `public`. – Jay Kariesch Dec 18 '20 at 20:07
Also updated with the next/image component. – Jay Kariesch Dec 18 '20 at 20:09
Removed the /public and require() and updated the post. Still doesn't work. Haven't tried the next/image component yet but looks promising. – Akhil Sukhthankar Dec 18 '20 at 20:20

It worked after I removed the extra / at the end of basePath. Thank you! – Akhil Sukhthankar Dec 18 '20 at 20:29
