createContext in a Server Component
Why This Error Occurred
You are using createContext
in a Server Component but it only works in Client Components.
Possible Ways to Fix It
Mark the component using createContext
as a Client Component by adding 'use client'
at the top of the file.
Before
import { createContext } from 'react'
const Context = createContext()
After
'use client'
import { createContext } from 'react'
const Context = createContext()
