Getting “ReferenceError: (x) is not defined” after passing object via props in Vue3

I’ve a vue page & vue component. The vue Page, is getting data via Firebase and passing hte object as a prop to a component. When accessing the prop, within the components template area, I don’t get any errors. But when accessing the same prop in the script setup, I get ReferenceError. Could you help me understand what I am doing wrong?

Vue Page:

<script setup lang="ts">
import { getProfile, profile } from '/@src/composable/useProfiles'

const params = new URL(location.href).searchParams.get('id')

onMounted(async () => { 
  getProfile(params);
})

</script>

<template>
  <div class="page-content-inner">
    <Core-MyProfile v-if="!params" />
    <Core-UserProfile v-if="params" :profile="profile"/>
  </div>
</template>

Vue Component:

<script setup lang="ts">
import { computed, ref, onMounted } from "vue";

const props = defineProps({
  profile: {
    type: Object,
    required: true,
  },
})

const sellPoints = props.profile.tribute.sell.current
const timePoints = props.profile.tribute.time.current
const usePoints = props.profile.tribute.use.current

const totalPoints = computed(
  () => sellPoints+timePoints+usePoints
);

</script>

Errors:
