All Inertia requests must receive a valid Inertia response, however a plain JSON response was received

Question

i am trying to understand and resolve this InertiaJs error without success i hope i can get some help here.

Answer 1

Maybe your are using this.$inertia, it waits for Inertia response;

this.$inertia.get(route('example'))
  .then(res => {
     console.log(res)
  })

Please use axios instead

axios.get(route('example'))
  .then(res => {
     console.log(res)
  })
