Error of "Trying to access the this of another class: tree.symbol" in typelevel scala but not in lightbend scala

[hamidr]

Hi guys,
I am trying to compile this particular file [1] but I encounter the following [2] error.
This actually compiles in the usual scala compiler without any error.
What do you think is wrong here?
[1]

package ptpUtils
import com.github.tminglei.slickpg._
trait PostgresDriver
    extends ExPostgresProfile with PgArraySupport with PgDate2Support with PgPlayJsonSupport with PgNetSupport
    with PgLTreeSupport with PgRangeSupport with PgPostGISSupport with PgHStoreSupport with PgSearchSupport {
  override val pgjson = "jsonb"
  override val api = MyAPI
  object MyAPI
      extends API with ArrayImplicits with DateTimeImplicits with PlayJsonImplicits with NetImplicits
      with LTreeImplicits with PostGISImplicits with PostGISPlainImplicits with RangeImplicits with HStoreImplicits
      with SearchImplicits with SearchAssistants {}
}

object PostgresDriver extends PostgresDriver

[2] The error message:
