A permission error occurred during the callback process from the HWP control PC to k1script.
k1script0
The callback from HWP, which had been specified in .ssh/authorized_keys, was commented out.
Since this was an emergency response, we first restored the original settings. Because the callback for the final move command was malfunctioning, we first performed a command-line callback from the HWP control PC to k1script0 to restore the callback that had been causing the permission error.
After that, we confirmed that HWP was responding correctly to commands from Guardian and performing the necessary processing.
