javascript - TypeError: r is not a function - next.js - Stack Overflow

I am trying to use a const from a context in my server side, inside /api. But when I use this, my backend console returns:

TypeError: r is not a function

and

SyntaxError: Unexpected end of JSON input

in the request that, without the context, works perfectly.

I also checked the variable before using it and it is returning the string it should. How to solve this?

'use client'
import { calendarInsertContext } from './calendarInsertContext'

export async function GET(req) {
  const { sdr } = useContext(calendarInsertContext)
  console.log('sdr backend: ', sdr)

• please provide the code where you have created context so that it will be more clear in debugging! – Abhishek Commented Feb 3, 2024 at 11:46

I have got the same error, apparently i had used 'use client' in my route.ts file which was not required.

it got resolved. it seems that vs-code will not throw any error indicator in file whether we use 'use client' in a file or not.

If you're using 'next-auth' latest(beta) version it's happen, so downgrade 'next-auth' with stable version it would be resolved.
