The BlueprintFileUtilsBPLibrary API is not accessible through python scripts run in the editor.

Attempting to run a script utilizing BplueprintFileUtilsBPLibrary results in:

LogPython: Error: Traceback (most recent call last):
LogPython: Error:   File "C:/Users/alex.berryhill/Documents/Unreal Projects/MyProject17/Content/Python/", line 2, in <module>
LogPython: Error:     unreal.BlueprintFileUtilsBPLibrary()
LogPython: Error: AttributeError: 'module' object has no attribute 'BlueprintFileUtilsBPLibrary'

This occurs in //UE4/Release-4.22 cl 8065155 so this is not a regression.

The Blueprint File Utilities plugin is no longer enabled in projects by deafult. It can be enabled by going to Window > Plugins and searching for 'Blueprint File Utilities'

Steps to Reproduce
  1. Create a new project
  2. Enable the Python Script Plugin
  3. Restart the project
  4. Using idle, create a new python script with the following lines:
    • import unreal
    • unreal.BlueprintFileUtilsBPLibrary()
  5. Select File > Save As
  6. Navigate to your projects content folder
  7. Create a new folder named "Python"
  8. Save the python script there as ""
  9. In the editor, open the output log
    • Window > Developer Tools > Output Log
  10. Select the dropdown menu in the bottom left corner of the output log
  11. Select Python
  12. In the field next to the dropdown type:

The module is inaccessible

The module is accessible through python script
