In order to solve this issue, the "Parse Error (...)" should be removed, so the description message only includes for example "Invalid characters in entity type". This is needed due to ParseError is an error in NGSIv2 (see http://telefonicaid.github.io/fiware-orion/api/v2/) reserved for error in the JSON parsint itself, so it is not a good idea to reuse the same words for BadRequest errors.

Fixed in #1236. @iariasleon please have a look and close the issue if you find it ok, please.
