I tried to get SfFileManager working, with Blazor server side. It works for me; I can brows my local disk, but sometimes I get Javascript-errors. It happens randomly, and I get different errors. I get a feeling it timing of initialization. It seams to happen less often when I show the browser console.
To get the errors I randomly refresh the page or press reload-button.
I basically took the sample code. I can provide the example.
I have attached the error log, but it mainly "Cannot read property "Item" or "PositionData" of Undefined.
