Not sure if this is the correct subforum for this. I have a piston that makes a http request to a generator controller on my LAN, then parses some JSON data to populate piston variables. This piston was running in my SmartThings webCoRE instance successfully for a year or so, then I migrated from ST to hubitat, and migrated the piston to a new webCoRE instance running on my hubitat hub.
The piston appears to be working occasionally, but sometimes returning JSON parsing errors. It is working well enough to correctly populate my piston variables, but I also am getting consistent log entries similar to this:

Is this a bug in the JSON parser or am I doing something wrong here?
