I have hit a blocking error when I try to generate the REST integration from the online LSA course, Lesson 6.1, Designing the Data Model, Exercise: Exposing integration using a data type.

I am using the Linux Lite version of the VM for this course.

Has anyone been able to generate the REST integration while running on the Linux Lite VM?
Or the regular VM?

Details

I am following the Detailed Instructions for the exercise. After I click to create the REST integration (step 6):

• I get a popup saying

“http://localhost:9080/prweb says

Generation process has been canceled and all created records have been removed”

• I dismiss the popup
• In the generation summary I see details
  “Canceling rule generation, Error evaluating rules using sample JSON stream”

I am using the Linux Lite version of the VM for this course, so I wondered about the possibility of a character conversion problem from Windows to Linux. However, I tried to generate a connector with a couple of other simple JSON files and got the same error.

One of the JSON files I tried was extremely simple:

{"book":[{"id":"01"}]}

I get the same result.
