Xporter 6.6.3 REST Export API: IndexOutOfBoundsException

[duracotton]

We are using Xporter 6.6.3 (currently the most up-to-date version).

When trying to use the Xporter Export REST API (https://confluence.xpand-it.com/display/public/XPORTER/REST+API#RESTAPI-SingleExportAPI) every request is being responded with the following error and stacktrace.

The API requests itself have been verified against the above documentation several times, so they should be correct regarding their syntax.

Any idea what is wrong? Do we miss a template?
