[BUG] Enum in query not resolving name correctly.

[frederikstonge]

Steps to reproduce

/api/enum-name-mapping-value0

Since this enum is used as query parameter, the default value is not resolving correctly, generating value0 instead of asc.

Expected results

SortDirection.asc as default parameter

Actual results

SortDirection.value0 as default parameter
