I am trying to embed tutor plugin **cairn** in my edx server.  
I have followed the instructions on the [github repo](https://github.com/overhangio/tutor-cairn)

On the final step `tutor local launch` the process fails and is exited. I am receiving this error bellow.

1. CAIRN\_CLICKHOUSE\_PASSWORD
2. CAIRN\_POSTGRESQL\_PASSWORD
3. CAIRN\_SSO\_CLIENT\_SECRET

and superset is not displayed

Your guidance is appreciated.  
Thanks in advance!

I’m having the same problem on my install. I tried upgrading the tutor version, but it didn’t work. Did you find a solution?  
Thank you for your help.
