Order creation is failing (required fields)
Problem
Insert Failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Missing value for required field(s). Order: []

STEP 1
Navigate to Setup
Create a NEW permission set, lets call it “Recurrex Order permissions“
Click on Object Settings
The permissions should look like this:
IMPORTANT: You don't need to update this unless you are seeing incorrect permissions for the Order object. In which case you will have to create a custom permission set with missing permissions and also assign it to the Salesforce user who is experiencing these issues.
