Engine options not working

Rancher 1.x

While adding a new host, I was unable to set engineInsecureRegistry and engineEnv.

It seems these parameters are just dropped when the JSON body is created, since they had a null value. I verified this in Firefox and Chrome.

Not only are there no errors reported in the UI, the host is added.

Has anyone else tried this?

Update: I successfully created a host with engineInsecureRegistry and engineEnv using the Rancher API, so it may just be a UI issue.

What version and machine provider? They seem fine to me:

4 
  Rancher v0.51.0
  Cattle v0.130.0
  User Interface  v0.78.0
  Rancher Compose  v0.7.0

And Openstack is the “provider”
