Generation code

enum class TypeIDs(val value: kotlin.String) {
        @Json(name = "0") _0(0),
        @Json(name = "7") _7(7),
        @Json(name = "8") _8(8),
        @Json(name = "9") _9(9),
        @Json(name = "10") _10(10),
        @Json(name = "11") _11(11),
        @Json(name = "12") _12(12),
        @Json(name = "13") _13(13),
        @Json(name = "14") _14(14),
        @Json(name = "15") _15(15),
        @Json(name = "16") _16(16),
        @Json(name = "19") _19(19),
        @Json(name = "-98") MINUS98(-98);
    }

Generated code has type String in the declaration (enum class TypeIDs(val value: kotlin.String)), however every entry is populated with an Int value (ex. _0(0), and not _0("0")), which results into a compilation error.

Any workaround for this? Or any expectation if this will be fixed?

This also can be reproduced with this openapi file: https://api-docs.jrni.com/v5/swagger/admin.json

(also with openapi-generator 7.2.0 version)

Still happening with 7.5.0
