Fix CalledProcessError

✅ Solution

CalledProcessError in ComfyUI usually stems from errors during external program execution, often due to incorrect file paths, missing dependencies, or command-line argument issues within custom nodes. To fix it, carefully examine the specific error message's stderr output, then ensure the external program is correctly installed and its path is set up properly in the executing custom node's code, and that all command line arguments passed to the external program are valid.
