The constraint is that the name of the group can only consist of alphanumeric characters.
Invalid example given: "1"
1 does not violate the constraint because it does not consist any non alphanumeric characters and seems to be a valid input.
If there are more constraints such as the length of group name, it can be included.
Currently, name with the same constraint accept "1" as a valid input.
