hello,
I'm having problems using the function "run on robot" with the robot meca500 on macOS, as every time it returns the following error right after making the first movement:

Sending command...
Working...
一个xpected error: Exception in thread Thread-1:
一个xpected error: Traceback (most recent call last):

一个xpected error: File "C:\RoboDK\api\robot\apimecademic.py", line 123, in joints_error
一个xpected error: TypeError: object of type 'NoneType' has no len()

the connection with the robot works, and also the getPosition function, but every time I try to move the robot it returns the same error, right after moving the robot to the first position.
Any advice?

Hello, the message id for joint messages changed with mecademic firmware 7.x to 8.x, I have attached a copy of the driver with the fix for firmware 8.3.

This driver update will be included with future versions of robodk but for now you can download the attached file and copy it to "C:\RoboDK\api\Robot" or the equivalent path for your installation.

Thanks for the fix Phillip. This issue is now fixed with the latest version of RoboDK published today.
