We've experienced rather frequent issues with Powerpoint files that are hard to pin down. In one case, it was a linebreak in a textbox, in another one an empty slide that caused the service to fail. The Java error message below doesn't provide much of a clue: ERROR com.matecat.converter.server.resources.ConvertToXliffResource - [CONVERSION REQUEST FAILED] null java.lang.NullPointerException at
