This simple script works from Blender (selects everything, deletes everything, inserts a camera), but fails from VS code - in the sense that it does select everything, and it also inserts a camera, but it doesn't perform the delete operation.

import bpy

bpy.ops.object.select_all(action='SELECT')
bpy.ops.object.delete(use_global=False)
bpy.ops.object.camera_add(enter_editmode=False, align='VIEW', location=(55,55,60), rotation=(0,0,0))

Here is a workaround:

bpy.ops.object.select_all(action='SELECT')
for obj in bpy.context.selected_objects:
    if obj.type == 'MESH':
      bpy.data.meshes.remove(obj.data)
    bpy.data.objects.remove(obj)

Fix for bpy.context.[active_]object set to None after adding primitiv…
a064dec 
…e when run from VS Code Extension JacquesLucke#135

# Summary of issue
Calling a script via operator results in an empty context.

https://devtalk.blender.org/t/how-to-run-a-script-from-outside-blender-script-live-link-addon/9792/3?u=jacqueslucke

# Solution
Use bpy.app.timers to register a function to run the target script.

# Changes
pythonFiles\include\blender_vscode\operators\script_runner.py
* remove the RunScriptOperator and move the contents of the execute method into a the `run_script()` function
* register a timer callback to the `run_script()` function that will execute the target script

# Potentially related issues
* When adding objects to collections the objects only show after the script ends. JacquesLucke#101
* accessing bpy.context.object crashes Blender JacquesLucke#86
* Crash when adding mesh JacquesLucke#63
* Delete is skipped JacquesLucke#68

# Testing
* execute a simple script that uses `bpy.context.active_object`
* set the #context.area:   SEQUENCE_EDITOR and run this script https://github.com/CGArtPython/blender_plus_python/blob/main/sequence_editor_frame_import/sequence_editor_frame_import_done.py
* execute the script from issue JacquesLucke#101 JacquesLucke#101
