Running rhoas service-account list works as epxected. and so does rhoas service-account list --size=100 as they are pretty much the same thing.

Something that is interesting though is when running rhoas service-account list --size=101 -v I get the following error.

{"fields":{"max":"must be less than or equal to 100"},"error":"invalid_field","error_description":"Request failed field validation"}

Wondering if we can have a custom error message for this as this just returns 400 without verbose mode.

Nice catch @jackdelahunt :). Unfortunately we dont have custom error message for this, but we can add client level validation to ensure page > 0 and size <= 100

Custom validations have been added @jackdelahunt
