RetrieveFormFields returns 0 fields on Blazor SfPdfViewer but js interop call can retrieve fields

Question

I've written a JS function to get the form fields from the loaded document

JS:

let pdfViewer = document.getElementById('pdfViewer1').ej2_instances[0];
let fields = pdfViewer.retrieveFormFields();

This returns the fields.

In the razor.cs when I try it,

var fields = await _pdfViewerFormFill.RetrieveFormFields();

There are no fields.

This is a problem since when I call _pdfViewerFormFill.ExportFormFields() the fieldsData don't have any values.
