Map property - nested case not working properly

[Abishek1726]

Hi can someone help me out? I am facing an issue in the map property matching nested case.

Mapper object (in Kotlin)

class Project {
    var name: String? = null
    var projectId: String? = null
    var customFields: Map<String,Any>? = null
    var ref: List<Project>? = null
}

Sql query

select 
  `ac1234`.`projectId` as `projectId`,
  `ac1234`.`name` as `name`, 
  `customFields`.`text1` as `customFields.text1`, 
  `customFields`.`text2` as `customFields.text2`, 
  `ref_ac456.customFields`.`udf12text` as `ref_ac456.customFields.udf12text`, 
  `ref_ac456.customFields`.`udf13text` as `ref_ac456.customFields.udf13text`
from `Project` as `ac1234`
  left outer join ac1234 as `customFields`
    on `ac1234`.`projectId` = `customFields`.projectId`
  left outer join ProjectMapping as `ref_ac456-0`
    on `ac1234`.`projectId` = `ref_ac456-0`.`rightprojectId`
  left outer join Project as `ref_ac456-1`
    on `ref_ac456-0`.`leftprojectId` = `ref_ac456-1`.`projectId`
  left outer join ac456 as `ref_ac456`
    on `ref_ac456-1`.`projectId` = `ref_ac456`.`projectId`
  left outer join ac456 as `ref_ac456.customFields`
    on `ref_ac456`.`projectId` = `ref_ac456.customFields`.`projectId`
where `ac1234`.`projectId` = 100

The following error is being throw by the simpleflatmapper

But mapping works fine when only one field is selected in Project inside ref object.
