MacOS – Different execution of bash script in ‘execute shell script’ action in Keyboard Maestro

I try to execute shell script using Keyboard Maestro.
In macOS Terminal and Raspberry everything works good. KM shows a strange error.
Looks like the script works but poorly recognizes characters or something.
Password saved in sha1 is correct.

KM with error:

Terminal with correct result on this same device:

Script (works on every device):

#!/bin/bash
# ------------------------------------------------------------------------------------------
# This script mimics the usage of the Home Wizard Lite app
# ------------------------------------------------------------------------------------------
# Dependencies: curl and jq (sudo apt-get install curl jq)
# It needs three parameters:
# - the SmartSwitch you want to control, between quotes (exactly as named in the Home Wizard Lite app)
# - the device you want to control, between quotes (exactly as named in the Home Wizard Lite app)
# - the action you want to perform, between quotes
# Depending on the device you control, one of the following actions may apply:
actionlist="On, Off, Up, Down, Left, Right, Stop, Favorite, Pair, ManualMode, AutomaticMode, DayMode, NightMode, GetState, Range, Open, Close"
# The fourth parameter is optional and indicates the time (in seconds) that the script will keep trying to perform the action.
# Example call: ./send_homewizard.sh "SmartSwitch1" "Controller1" "On" 60
# ------------------------------------------------------------------------------------------
# You have to fill in your HomeWizard Lite username and the sha1-hash of your password between the quotes:
username="mymail@gmail.com"
password_sha1="4bg7j41b3785d06465b507790z09drge96414386" #can be generated on https://hash.online-convert.com/sha1-generator
