learning records REST API get no data (only for offerings)

Summary:

We use the "Get all assignment records" to get specializations and courses, but we can`t get offerings.

The url is https://ourpod.com/hcmRestApi/resources/11.13.18.05/learnerLearningRecords?finder=findByAssignmentRecordId;assignmentRecordId=300002190689120,dataSecurityPrivilege=ORA_LEARN_SPECIALIST

We wrote a query to get the assignmentRecordId so we are sure the id exists

Is something missing to get the record?
