Steps to reproduce

1. Start a clean bundle of Liferay DXP 7.1 installed with dxp-13 and hotfix-2521.
2. Go to Content -> Forms -> Options -> Data Providers and create a new Data provider with the following fields:

       Name: restcountries
       URL: https://restcountries.eu/rest/v2/region/{region}?fields=name
       User name: test
       Password: test
       Inputs - Label: region
       Inputs - Parameter: region
       Inputs - Type: Text
       Outputs - Label: name
       Outputs - Path: $..name
       Ouputs - Type: List
   

3. Create a new form with the following field names and field types: Region (Text), Countries - From Autofill (Select from List), and make all the fields required
4. Add the following rule to the form: If Region is not empty, Do Autofill from Data Provider: restcountries, region: Region, name: Countries
5. Add a forms portlet to a page and add this form
6. Type polar into region, and verify that Antarctica automatically populates
7. Select "Choose an Option" in the Countries line
8. Submit the form

Results of Testing
