Winforms C# .NET API Signature Cursive

Hi friends,

I have an issue with signing data from the web interface. DatePicker fails on open and I can`t select date.
Javascript error "TypeError: Cannot read properties of null (reading 'length')";

I using VS2019, C#, WebView2 component

Hello All, I am completely new to eSign and to e-signature generally. I am a C# .NET developer and wondered if any of you can share some knowledge. For test purposes (i.e. assessing Vasco eSign for suitability for our application) I would like to put together a small Winforms app in C# .NET using the appropriate API. I want the app to accept a cursive signature; i.e. a normal human signature via touch screen, pen, etc. As this is going to run on a PC, I won't be able to do the signature in the normal way but purely in order to understand the API etc.
