DEV: Bug: Device Cloud does not work when there is only a single allocation variable

This seems to be that the api call to "all variables containing 'ONLINE_AND_AVAILABLE' returns an array for multiples and a scalar for a single variable.

It DOES work with a single online runner gateway as long as there is multiple variables. For instance, while I was testing a cloud with only one runner gateway, I just created a second, completely fake CI/CD variable in the pool management project and it started working.
