Dynamic Input and Function Scripts fail to compile by default

All Niagara Scripts are uncompiled by default. This has been logged ([Link Removed]).
Compiling the script resolves the warning noted in 66593 for Module and Function Scripts. Dynamic Input Scripts, however, have a persistent compile error that remains after the initial compile.

1. Open any project in UE4Editor
2. Select > Edit > Plugins > FX

7. Compile the Dynamic Input Script

Result:
