JSON.parse unexpected error

I am making a MERN stack app where I have made a DB using Mongo Atlas and using node.js and express to fetch the data in my react app. I am calling the data using an

useEffect()

useEffect()

and awaiting the data as well. When I am trying to convert the data into json, it is giving me the error of

Uncaught (in promise) SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

Uncaught (in promise) SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

I am stuck here and cant solve this. I tried many different posts on net but none worked for me.
The backend server is running on

localhost:4000

localhost:4000

and react app is on

localhost:5173

localhost:5173

. I tried

CORS

and even adding a proxy in

package.json

but that also didnt work.
