Hey guys! Hoping you could help with this one.

I have the following exception occurring:

Error: Exception in thread "main" java.util.NoSuchElementException: List is empty.
	at kotlin.collections.CollectionsKt___CollectionsKt.first(_Collections.kt:221)
	at com.cjbooms.fabrikt.generators.PropertyUtils.addToClass(PropertyUtils.kt:144)

Error: Process completed with exit code 1.

Checking the fabrikt generator, it happens within this function on line 144 in PropertyUtils.kt

I verified that my spec file doesn't have discriminators with only one value in them. Obfuscated it looks like:

        "discriminator" : {
          "propertyName" : "something",
          "mapping" : {
            "ABUG" : "#/components/schemas/Bug",
            "INARUG" : "#/components/schemas/Rug"
          }
        }

So it looks like a discriminator exists and the .first() function is not finding it on line 144, I don't know why this would occur.

If you'd like I can email the whole spec file to someone, or you can email me to request it.
