If a role is duplicated and only one has a group, do not include the duplicate.

What you're doing here may work for your examples, but the logic is not quite right. There may be more than one that has different groups. What you want to do is have a "key" that takes into account the "identity" of the role independently of the group. Internally the java hashcode function uses relatedCode,relatedName,type,source. So the idea is to put them into a set based on a hash key and then extract that back to a list. something like this

const key = o => JSON.stringify([o.relatedCode, o.relatedName, o.source, o.type]);
this.roles = [...new Map(input.roles.map(o => [key(o), o])).values()];
