Installation Fails for Koa.master, Koa.1 and Koa.2 with "KeyError: 'PREVIEW_LMS_BASE'"

Hi @Gaurav_Vijayvergia,

We’ve done some testing around the new koa.2a tag yesterday, and none of us ran into this particular issue. Did you follow the native installation instructions? If so, did you do anything different? Any settings that are different from the default, perhaps?
