Bad request (400) from EMS 5.x when querying LocalEms for isConnected property

Hello,

I'm having an issue with EMS 5.3 (actually 5.x). Get isConnected from LocalEms returns a bad request error. The only time that isConnected works is if I do it prior to querying one of my things, but as soon as one of my things is called, then I get the 400 bad request from the EMS.

Here is the conversation:

Here are the errors logged in the event viewer:

and

Expected 18 bytes of content but got 0

Do you know what could be the issue here ?

Thank you.
