Which function call throws the exception?

To avoid it, check the condition before calling the function. Alternatively handle it inside the catch statement.

You cannot 'resolve' the exception: you catch it and handle, in the catch block, the error.
If there is 'no row at position 0' then you probably have a failed query. Depending on your scenario you could inform the user of the failure, or terminate the application or attack the pirates or whatever...
