Trying to change node_type on AWS leads to ERROR: release required

Hi, when I do:

convox rack params set node_type=c5.large    

I then get:

Updating parameters... ERROR: release required

Okay, so I must have to get some rack releases, I guess. So, I type:

$ convox rack releases
ERROR: release history is unavailable

Not really sure where to go with this. Any ideas?

@scott1 I’m also running into this with a new v3 rack. Were you able to figure this out?
