[~Zentol]  i use blink planner.

in flink planner,there is not that function call.the code is 
{code:java}
val (physicalName, idx, tpe) = resolveInputField(name, tableSource) 
// validate that mapped fields are are same type 
if (tpe != t) { throw new ValidationException(s"Type $t of table field '$name' does not " + s"match with type $tpe of the field '$physicalName' of the TableSource return type.") } idx
{code}
 while,in blink planner
{code:java}

 val (physicalName, idx, tpe) = resolveInputField(name, tableSource)
 // validate that mapped fields are are same type
 if (!isAssignable(fromTypeInfoToLogicalType(tpe), t)) {
          throw new ValidationException(s"Type $t of table field '$name' does not " +
            s"match with type $tpe of the field '$physicalName' of the TableSource return type.")
        }
        idx
{code}
