vscode attached to Docker container - module not found

Question

I'm running vscode debugger inside Docker container but it started showing an error:

That is very strange because when I open python shell in the same vscode window and import the same module import works just fine. So I need to find the reason why debugger doesn't see the modules

The full error code:

My debugger config file launch.json

    {
      "name": "Python: File",
      "type": "python",
      "request": "launch",
      "program": "/opt/HonkioServer/entrypoints/api2/docker_entry",
      "justMyCode": true
    }

Answer 1

Finally I found the source of this issue - it was in the file that directly imported to docker-entry file and modules from project directories were imported in a strange way:

# This line adds to modules imports that added below cd two levels up
sys.path.insert(0, os.path.dirname(__file__) + "/../..")

import honkio

However, right after I change this file in vs code, formatter changed lines order automatically placing that line at the bottom of all the other imports. Therefore file imports break and it shows module not found error
