FYI, this error has really been resolved.

Deployed a fix under version 1.1.3., for more info see Stack Overflow:

Updated the user doc:

He is certain he is passing the correct value as he is able to execute the same query in raw format, so he believed it has to do with the way params are implemented. I'm no expert but he said it looks like an error from C language.
