I created some vector polygons, added there field height, fill it with values. After it using polygon to raster converted it to polygon (specified that value field to height).

Than I got rasters.

But when I called Viewshed. I got error: All cells in raster have the NODATA value.

I believe the error is due to your point being on a NODATA cell. How can you do a viewshed if you do not know your height? View sheds are traditionally run on surface DEMs, where every cell has an elevation height. So your input data makes no sense. Suggest you read the Help file to understand the inputs and viewshed concepts.
