How can i solve rosgenmsgs index error on matlab2023b about xarm by Ufactory

Hi, Here is RIKUTO OSHITA.

I am now having trouble with a custom ROS message error regarding xarm in Ufactory.

I cloned xarm_ros from official git and tried to generate "xarm_msgs" in it as custom ROS messages in MATLAB.

However, I get the following error and cannot proceed.

"The index exceeds the number of array elements. Index must not exceed 1."

The folderpath seems to be correct.

I also think that the message is not wrong, since the actual device can be operated via ROS topic communication on the terminal.

If anyone has a better answer, please let me know.

Kindly wait for your help.
