OnTheGo/API: Unhandled exception error

Issue

The OnTheGo application crashes immediately after connection and produces an ExceptionAttributes:15:ERROR:UNHANDLED EXCEPTION Cannot convert type 'string' to 'int' or something similar.

If you are seeing a crash immediately after connection to OnTheGo (Connection succeeds, but information does not pass), then we need to examine the exact error code coming up.

Solution

The process of connection for OnTheGo follows is:

To connect to OnTheGo

Connect to database
Query Default Profiles from database
Start opening other data.

This kind of error is probably symptomatic of a default profile having string information (Alpha characters) instead of Integer information (numbers) stored against it.
