“The requested name already exists as a different type” HTTP 409 response error

Question

I'm trying to implement a WireCloud widget which communicates with ObjectStorage via JS ObjectStorageAPI . After some troubles with enabling ObjectStorageAPI i've manages to run command os_api.listContainer() and in response I've got 409 error, with message attached "The requested name already exists as a different type" . I've been trying to find bugs in my code for last few days and nothing seems to be wrong with it. I'm trying to run widget using FiWareLab as a working environment. Does anyone have any idea about what could be causing mentioned error?

EDIT: I've managed to figure out what is causing this error. In order to list a container, cdmi request url must end with "/" character. When I use os_api.listContainer() it generates url without it. If I manually append url proper response is returned with container's contents.

First idea of fixing it - to append "/" to container's name - doesn't work. "/" character is replaced by escape sequence "%2F". Not sure if there's a way around this issue?

This clearly is a bug in the Object Storage API provided by WireCloud. Please, send an email to fiware-tech-help@lists.fi-ware.org for creating a ticket in the FIWARE's help desk tracker.

I'm not able to provide you a temporal workaround, sorry, but we are working on fixing it and with a bit of luck it will be fixed soon.

Update: The bug was fixed on the source code of WireCloud, and the FIWARE Lab's Mashup portal has been updated with the fix.
