    'The argument value is not valid' error on import project with FluentBooks


    While importing project with FluentBooks, you may get the following error:

     ERROR Project "Test Project" import error
    (Exception) TargetInvocationException: Exception has been thrown by the target of an invocation.

    This issue may indicate to corrupted local cache in Project Pro.


    1. Clean Cache from Project Pro. To do that, go to File → Options → Save → Clean Up Cache.

    2. We would also recommend cleaning the following folder before starting the migration.

    %Appdata%\Microsoft\MS Project\16\Cache
