src/main/kotlin/org/wfanet/measurement/kingdom/service/api/v2alpha/AccountsService.kt line 98 at r1 (raw file):

          else -> throw Status.UNKNOWN.toExternalStatusRuntimeException(ex)
        }
      }

nit: can extract some common code from this for less repetition

Suggestion:

      } catch (e: StatusException) {
        throw when (e.status.code) {
          Status.Code.NOT_FOUND -> Status.NOT_FOUND
          Status.Code.PERMISSION_DENIED -> Status.PERMISSION_DENIED
          else -> Status.UNKNOWN
        }.toExternalStatusRuntimeException(e)
      }
