I make a stepper formik form and the objective is yup should validate each step of the form. this is my validation schema:

const schema = [
yup
  .object()
  .shape({
    field1: yup.string().required("cannot be empty"),
    field2: yup.string().required("cannot be empty"),
  }),
yup
  .object()
  .shape({
    field3: yup.string().required("cannot be empty"),
    field4: yup.string().required("cannot be empty"),
  }),
yup
  .object()
  .shape({
    field5: yup.string().required("cannot be empty"),
    field6: yup.string().required("cannot be empty"),
  }),

];

<Formik
    initialValues={initialValues}
    validationSchema={schema}
    onSubmit={_handleSubmit}
  >
    {({ isSubmitting, dirty, isValid, values, resetForm }) => (
      <Form>// ........ rest of the code</Form>
    )}
  </Formik>

but i got error massage “schema[(intermediate value)(intermediate value)(intermediate value)] is not a function”. how should i setting up he validation schema?
