Hi! I'm having this problem as well. Help would be appreciated! Here's the stack...

Hi, I don't know if it will help you but i had this error too and i fixed it even if i don't really why it was creating this error.

in my apollo-client init i'm using apollo-link-state and i had this init :

// apolloClient.ts
[...]
import { withClientState } from 'apollo-link-state'
import { defaults, resolvers, typeDefs } from './resolvers'
[...]
const stateLink = withClientState({
  cache,
  defaults,
  resolvers,
  typeDefs,
})
[...]

// resolvers.ts
export const defaults = {
  isConnected: true,
}
export const resolvers = {
  Mutation: {
    updateNetworkStatus: (_, { isConnected }, { cache }) => {
      cache.writeData({ data: { isConnected } })
      return null
    },
  },
}

export const typeDefs = {}

to fix the error i simply change my typeDefs :

// from
export const typeDefs = {}
// to
export const typeDefs = ``

After that change, everything worked again. I hope that helps :)
