I’m trying to add a WhiteList rack param, however I’m getting this error:  
`Updating parameters... ERROR: direct rack doesn't support update, make sure you are not using RACK_URL environment variable`

I’ve tested this on several different rack params and I’m getting the same error for all of them. Can someone please advise on what is going wrong here?

For context, my cli command is: convox rack params set WhiteList=

Thanks!

Hey Luke,

It seems like you’re trying to directly call the rack API. Can you please run `convox switch rackName` and attempt to run the command again.

If that doesn’t work can you please attempt to login to the CLI in a new terminal and test again.

Also just to make sure you’re using the correct command it should be  
`convox rack params set whitelist=ip/cidr#,ip/cidr#`  
e.g.  
`convox rack params set whitelist=10.20.0.0/8,172.80.80.0/24`

Regards,

Hi Nick,

I am having the same issue. Brand new v3 rack on GCP. Though before I always explicitly wrote the name of the rack for every command (prefer it that way), I used `convox switch` to see if it would help and still getting the same error. It works fine for v2 racks.  
`convox rack parameters` doesn’t print out anything (not even an error). It works for v2 racks.  
I can’t see any parameters in the Convox Console either.

Not sure how to proceed here.

The issue was that I used Convox CLI v2 instead of v3.
