TypeError: Cannot read property 'MongoClients' of undefined

Hi everybody,

I'm trying to run my tests with testexecute, but when I run tests I got an error: 'TypeError: Cannot read property 'MongoClients' of undefined'.

I imported java mongo classes in my current project.

This  is the line where i call object Mongoclients.

var mongoClient = JavaClasses.com_mongodb_client.MongoClients.create_4(DBConnectionStrAzure);

Why in my project work and in another pc with testexecute not?

Thanks
