[Fiware-tech-help] FIWARE - base64 format not supported in JSON?

[Juanjo Hierro]

Dear José Ramón,

   Thanks for the info about the problem.

   I copy the fiware-tech-help channel in my response to make sure we 
keep track of this issue.

   I also copy Jason Fox who has more experience with IoT Agents and 
perhaps has faced the problem, know how to solve it or, alternatively, 
can forward this to the team at Telefonica that is the major caretaker 
of the IoT Agent JSON you mention.

   I understood in a previous conversation that you had raised this 
issue in Stack Overflow .. may you provide the link to the issue 
raised?   I'm saying this because perhaps it is worth to respond (once 
the solution is found) through Stack Overflow.

   Cheers,

   Juanjo
