I followed the article https://community.pega.com/knowledgebase/articles/whats-new-pega-platform/explore-react-ui-runtime-environment-84 but it seems to not have detailed steps. I have done below changes in Pega labs 8.4 environment but could not find a way to launch the react UI previewOption 1:1) Created a new application in Pega 8.4 which is built on core pega platform , enabled 'Support React-based UI' option on the application rule2) Updated the DSS pega-uiengine!constellationsvcurl as /prweb/constellation , assuming that Pega labs should use the load balancer3) On UIservice service package , 'Requires Authentication' was unchecked , so did not enable it4) Logged in with admin user and changed to App studio or logged directly with user credentials who has access to app studio , none of the option launches the ReactUI preview tool Option 2:1) Created a new application in Pega 8.4 which is built on COSMOS , enabled 'Support React-based UI' option on the application ruleRest of the steps remain same.

Posted: 6 months agoKevinZheng_GCS PEGA replied to Suman PalukuruIf you are using pegalabs, please check with the admin to see if the constellation service is configured or not. Normally you have to run a docker container to start the constellation service: https://community.pega.com/sites/default/files/help_v84/procomhelpmain.htm#designer-studio/installing_the_docker_container_with_react_ui-tsk.htm Accepted Solution Posted: 6 months agoSuman Palukuru Tata Consultancy Services Ltd replied to KevinZheng_GCSThanks for the reply Kevin.
