When I try to run Mission Planner’s built-in simulation (currently I want the plane sitl but this problem occurs for each vehicle), I get an error starting with the following:
An error has occurred
Newtonsoft.Json.JsonReaderException: Unexpected character encountered while parsing value: T. Path ‘ArduCopter.frames.IrisRos.external’, line 109, position 28.
Complete error message is shown in the screenshot below.
I appreciate any help, thanks in advance.
