/**
 * Here we can define our exception map. Order is important - first matched exception will be used.
 * We can match exception in two ways:
 * - as exact hit (when our caught exception class is the same as the one in the map)
 * - as instance (when our caught exception is an instance of the one in the map)
 * In the Map we can set all the values we want to use in the response and define onCatch and formatter closures
 * used to successively:
 * - add action on catch (eg. report exception to somewhere else)
 * - and format the response (eg. modify error message depending on details):
