Case construction in getopts doesn't work

Question

When I put an option in the middle, the case doesn't work. After, the script continues to work.

while getopts "t:target:" opt; do
  case opt in
    t)
      test = "$OPTARG"
      ;;
    target)
      ;;
    \?)
      echo "Invalid option: -$OPTARG" >&2
      exit 1
      ;;
    :)
      echo "Option -$OPTARG requires an argument." >&2
      exit 1
      ;;
  esac
done

echo $TEST

if [[ "$2" != "-t" && "$2" != "-target" ]]; then
  echo "The -t or -target option must be the second argument."
  exit 1
fi

When i am doing :

./myScript file_path -t

I am getting :

realpath: '': No such file or directory
Directory not found at the second given path :

But normally it would work :) - case option

option requires an argument -- o

Please, help)
