Docker dev sandbox has no state?

[Aaron Horne]

HI there, I'm just trying to get my smart on fhir app running from a locally run smart on fhir sandbox (https://github.com/smart-on-fhir/smart-dev-sandbox)  but when I launch my app from the launcher,  I'm not getting a state param which is causing an oauth2 failure which puts me into an endless loop at the login screen:

Here is a console log of my URL params as received:

RAW URL Params: launch=eyJhIjoiMSIsImYiOiIxIn0&iss=http%3A%2F%2Flocalhost%3A4013%2Fv%2Fr4%2Ffhir

There is no state param which is putting me into this endless loop. What am I doing wrong? If you go to the public sandbox https://launch.smarthealthit.org/  the state param is present. Any thoughts? 

Thanks!
