Error in the settings.json file.

[spflanze]

I followed the directions, and the example, on page:
https://github.com/mkloubert/vs-deploy/wiki
I do not have a package, I only have webpatges I need to upload, and website mirrors on my local hard drive that needs to be synced with the server at my hosting service from time to time. Visual Studio Code indicated an error I could not figure out the cause of. So I decided to past in the relevant part of the example in the webpage linked to above. I got the same error. This error is shown in this screen shot:

As can be seen, there is on the first square bracket after "host":, an "Incorrect type" error. Is this an error that needs to be paid attention to?

Since this is an sftp target, it will require a private key. I do not see in the example a way to enter it. How is that entered?

When a webpage's edits are done and saved on the hard drive, how is the webpage uploaded? I do not see an option to do that from the Deploy extension in the menu that appears when I right click the mouse.
