Hi,

I have been blocked by a problem using the "Assistant Node" returning this message:  
Error: Unauthorized: Access is denied due to invalid credentials.

The solution was working well before the end of december 2019.

My problem is to keep the session alive: is there any way to solve this problem?

Thanks in advance for your help.
