How do i debug database related error in Agiletookit ? ATK4

Question

I know about the $m->debug(); as mentioned here

But i am not sure how i should start debugging the following issue. My approach will be doing a var_dump inside dsql.php and compare fields and then go step by step upwards in the OOP layers. I was wondering if there was some easy way to do the same thing.

Actual Error:

/Users/Qambar/Work/VERYCOOLAWESOMEPROJECT/atk4/lib/DB/dsql.php  :1518   bozims_db_db_dsql_mysql DB_dsql_mysql-  >exception("Database Query Failed")

Usually - do a debug() which will give you a query itself. Copy-paste query into SQL console. If you get error there, then try to understand why.

You can also use setActualFields to narrow down list of fields queried, which will make your query simpler.

That should help you narrow down the problem.
