JSON document that will instantiate the variables at the local scope of the error catch
event that catches the thrown error; it must be a JSON object, as variables will be mapped in a
key-value fashion. e.g. { "a": 1, "b": 2 } will create two variables, named "a" and
"b" respectively, with their associated values. [{ "a": 1, "b": 2 }] would not be a
valid argument, as the root of the JSON document is an array and not an object.
