Hello Jonathan,
First re verify the documentation about this connector :
https://docs.mendix.com/appstore/modules/aws/aws-iot-sitewise/
Did you install the prerequisite ?
Next try to import the module again maybe you need a newer version.
Then if it all not works create a blank project and just import the modules there and check whether you can run it there, if that is possible then check the userlibs which ones do you need and which ones do you have in your project; and which ones are conflicting.
Hope this helps,
Good luck!
