How do I find out what doesn't work?
I'm currently trying to understand how visuals are developed per TypeScript. My experience with programming is mostly limited to C# in school - so not that much. That means that I'm having a lot of troubly unterstanding it completely.
In order to pick up the way visuals are created, I wrote the simple bar chart myself - by copying it line by line, and looking at what everything does. It helped me a lot. When I start the server, load the developer visual, and add data to it - nothing happens. Only the update count goes up.
The config/capability files are all the same as in the github example. The barchart code is the same, too.
How can I "debug" this file? How do I find out, what is going wrong?
EDIT: Editing to say, that I have tried debugging.
You should use module instead of namespace:
namespace powerbi.extensibility.visual
As a result you should have this:
module powerbi.extensibility.visual

Make sure you run command in the right visual project and the file name in tsconfig.json is correct. To debug your visual, use the try...catch statement.

Hello, thank you for your time.
I have already tried debugging, but there were no errors. When I try compiling my code with pbiviz start, it throws this error in the .tmp/precompile/visualPlugin.ts file:
{Projectname} is not a property of "Visual"
The filenames/-paths in pbiviz.json and tsconfig.json are right.
Did you fill capabilities.json?
Could you please share your current code?
