I tried to follow this tutorial: <a href="https://help.liferay.com/hc/en-us/articles/360029134351-Data-Providers">https://help.liferay.com/hc/en-us/articles/360029134351-Data-Providers</a> which guide on how to retrieve drop-down list values (list of countries) from Liferay built-in REST service in Liferay forms.However after I entered all the details and saved, i got this error: &#34;URL must not be a local network&#34;.<br />FYI, I run Liferay 7.2 in my localhost and managed to see the REST service values (<a href="http://localhost:8080/api/jsonws/country/get-countries/">http://localhost:8080/api/jsonws/country/get-countries/</a> )  if i opened it in browser. Any ideas what I did wrong? Thanks. Izzat Helmi 2020-09-07T03:53:06Z
