VSCode issue. ninja: error: loading 'build.ninja': No such file or directory

[IIIapcep]

I'm trying to build "application_update" sample. I created a new application from sample. added build configuration for nrf9160dk_nrf9160_ns board and changed to variables in prj.conf: 

CONFIG_DOWNLOAD_HOST and CONFIG_DOWNLOAD_FILE.

The build always failed due to error: loading 'build.ninja': No such file or directory.

SDK v.1.8.0

Command Line Tools v. 10.15.0

Can you please advise how to fix it?

SOLVED

when creating the  sample from the VSCode interface, the "common" folder is missing in the root directory. Just copied from git repo: https://github.com/nrfconnect/sdk-nrf/tree/main/samples/nrf9160/http_update/common. It is pasted in the root directory. Re-build the project.

it works now
