無法在 Mac 上的 Cronjob 中執行 Bash 腳本

下面的腳本可以從普通用戶執行，但我無法在 macos(bigsur) 上透過 cronjob 運行腳本：透過作業安全執行腳本時出現以下錯誤：SecKeychainSearchCopyNext：在鑰匙圈中找不到指定的項目

#!/bin/sh

keychainItem="connectvpn"
# this name has to match "Account" for the entry you make in keychain
VPNName="DIS CVPN"   # match the name of the VPN service to run
function isnt_connected () {
 scutil --nc status "$VPNName" | sed -n 1p | grep -qv Connected
}

get_pw () {
   security 2>&1 >/dev/null find-generic-password -ga $keychainItem \
   |ruby -e 'print $1 if STDIN.gets =~ /^password: "(.*)"$/'
}



echo "fetching VPN credentials from keychain account \"$keychainItem\""
echo "Using VPN service: $VPNName"

if isnt_connected $VPNName; then
 echo "Connecting to VPN..."
 scutil --nc start "$VPNName"
 sleep 1
 osascript -e "tell application \"System Events\" to keystroke tab"
 osascript -e "tell application \"System Events\" to keystroke \"$(get_pw)\""
 osascript -e "tell application \"System Events\" to keystroke return"
else
 echo "Already Connected to VPN..."
fi

這是我的 crontab 行：

*/1 * * * * /Users/demo/vpn/connect.sh >> /Users/demo/vpn/vpnlog.log 2>&1
