Why is the exception not being caught?

Question

Dart

There is the following Dart code:

try 
{
  print("!1111111111");
  await db.KVToTableInsert(tableToInsert);
  print("!2222222222");
  return dbEnums.success;
} on PostgreSQLException 
{
    print("Fail is here");
}

It crashes in the console:

!1111111111
Unhandled exception:
PostgreSQLSeverity.unknown 23505

Tried catching:
on Exception {print("Base Exception");}

Current implementation of the insert method:

KVToTableInsert(String tablename, Map jsonMap) async {
    // print(jsonMap);
    List insertNoticeKeys = [];
    List insertNoticeValues = [];
    jsonMap.forEach((key, value) async {
      if (value is List) // nested
      {
        value.forEach((item) async {
        await KVToTableInsert(key, item);
        });
      } else {

Everything seems to be correct with async/await?

But it didn't help either. What could be the reason?

try instead on Exception-catch(e)
