Python file cannot be executed with exec node.

I did it the same way before.

After formatting and updating the Raspberry Pi, the Python file cannot be executed in the exec node.

It works fine in cmd, but not only in node red, what is the reason?

/usr/bin/python /home/pi/soil/soil.py

The argument is 0x20.

have you flagged the file as executable by the same user that is running node red (presumably pi ?)

Connect debug nodes to all outputs of the exec mode, set them to show Complete Message and carefully check all the outputs. You should find more information on the problem.

Strangely, it seems that there is a problem with the Raspberry Pi. Format it and try again. Thank you.
