@dmoranj @dcalvoalonso @fgalan
This was fixed as part of #273 and should be closed

[fgalan]

For me is ok to close it but maybe @jmcanterafonseca (the original reporter of the issue) should do it.

Hi @jmcanterafonseca can you close the issue as it is fixed in latest build. Hi @fgalan , the issue can be closed what's your opinion on this.

I think the ongoing work on documentation re-working (issue telefonicaid/iotagent-node-lib#1329) makes this issues obsolete. We are going to close it. @Keshav-NEC thanks for raising it!
