EDIT:

Add your content inside another <section> tag.

---

I recently did work with this library, and this is my base component that renders different content (code below).

The only real difference I see between our code might be the await on the function that generates the PDF.

Try that, but if it doesn't work, you might try and copy paste my code below and see if it works (Just replace the <slot/> with whatever you want, and add some boilerplate for the props).

<template>
    <div class="pdf-converter">
        <BaseButton
            class="mt-auto text-white h-13 bg-blue"
            :disabled="disableButton"
            @click="$emit('generate-pdf')"
        >
            {{ buttonText }}
        </BaseButton>
        <VuePDF
            ref="html2pdf"
            :show-layout="false"
            :float-layout="false"
            :enable-download="false"
            preview-modal
            :paginate-elements-by-height="1400"
            pdf-content-width="700px"
            :filename="fileName"
            :manual-pagination="false"
            pdf-format="a4"
            :html-to-pdf-options="pdfOptions"
        >
            <section
                slot="pdf-content"
            >
                <div
                    v-if="show"
                >
                    <slot />
