page: 1,
xPercent: 10,
yPercent: 10,
angle: 0,
sections: {
'type!{urn:appian:ps:pdftools}PdfSection'(
style: null,
components: {
'type!{urn:appian:ps:pdftools}PdfText'(
value: "Some"
),
'type!{urn:appian:ps:pdftools}PdfText'(
value: "text"
)
}
)
}
)
}

but I try to pass a pv! as value into the contents I got this error
