vue3-html2pdf generates blank pdf

[joyal7701]

this generates blank pdf for me:
<vue3-html2pdf :show-layout="false" :float-layout="true" :enable-download="true" :preview-modal="true" :paginate-elements-by-height="1400" filename="invoice" :pdf-quality="2" :manual-pagination="false" pdf-format="a4" :pdf-margin="10" pdf-orientation="portrait" pdf-content-width="800px" @progress="onProgress($event)" ref="html2Pdf" > <section slot="pdf-content"><div>hii</div></section> </vue3-html2pdf>

Function:

<img
:style="{ cursor: 'pointer' }"
src="../assets/images/download-arrow.png"
alt="«"
@click="generatePDF()"
/>

generatePDF() {
this.$refs.html2Pdf.generatePdf();
},
