Component-Based Error Handling (SSR)?

<NuxtErrorBoundry> component handles client-side errors happening in its default slot. But its not works on ssr. We are getting the ugly error page if the page that contains error is rendered on SSR. I want to my whole page to be rendered except the component that throws an err. Is there any way to handle this?

For those who looks for a solution, this works perfect on both csr and ssr!!! components/ErrorBoundary.vue

<script setup lang="ts">
const error = ref<Error>()

function clearError() {
  error.value = undefined
}

onErrorCaptured(err => {
  error.value = err
  return false
})

const route = useRoute()
watch(
  () => route.fullPath,
  () => {
    error.value = undefined
  },
)
</script>

<template>
  <slot v-if="!error" />
  <slot v-else name="error" :error="error" :clear-error="clearError" />
</template>

<script setup lang="ts">
const error = ref<Error>()

function clearError() {
  error.value = undefined
}

onErrorCaptured(err => {
  error.value = err
  return false
})

const route = useRoute()
watch(
  () => route.fullPath,
  () => {
    error.value = undefined
  },
)
</script>

<template>
  <slot v-if="!error" />
  <slot v-else name="error" :error="error" :clear-error="clearError" />
</template>

How to use

<error-boundary>
  <nuxt-page v-bind="$attrs" />
  <template #error="{ error, clearError }">
    <p>{{ error }}</p>
    <button @click="clearError">Try again</button>
  </template>
</error-boundary>

<error-boundary>
  <nuxt-page v-bind="$attrs" />
  <template #error="{ error, clearError }">
    <p>{{ error }}</p>
    <button @click="clearError">Try again</button>
  </template>
</error-boundary>
