The tenants variables page is showing an System.ArgumentNullException: Value cannot be null. Parameter name: key
I’m using Octopus 3.4.2. It did work, but when I changed some settings this error appeared. Reverting back to the configuration that worked doesn’t solve the problem.
Situation: We have multiple environments on one machine. Like Test - Client 1, Test - Client 2.
Before Tenants we used this to deploy different client instances on one machine. For a new project I used tenants. I decided to use Test - Client 1 environment and made a project variable. I set the variable for tenant 1.
With tenants the multiple environments shouldn’t be needed anymore, so I created a Test environment on the same machine.
I added Test to the lifecycle, Test - Client 1 environment still active also.
In the tenants overview I changed the project environments to the Test environment.
Now moving to the variables page shows the error.
