I have Elastic and Kibana running successfully. Now I’m unsure how to launch the development version. I went to the directory in WSL and used the “yarn start” command. I have updated the kibana.yml file to reflect the version that is running on my local machine. I am getting the following warnings and can not connect with a browser:
