Applescript ไม่ทำงานบน High Sierra

ฉันสร้างรหัสแอปพลิเคชันเพื่อช่วยเปลี่ยนชื่อรูปภาพจำนวนมากและสร้างไฟล์ข้อความที่มีชื่อไฟล์และส่วนข้อมูลเพื่อให้เราสามารถส่งออกไปยังทีมอื่นเพื่อตั้งโปรแกรมเป็นอีเมล

รหัสทำงานได้อย่างสมบูรณ์แบบเมื่อฉันอยู่ใน Sierra แต่ตั้งแต่ฉันอัปเดตเป็น High-Sierra มันไม่ได้เปลี่ยนชื่อไฟล์ทั้งหมด โดยปกติแล้วอีเมลของเราอาจมีภาพ 4-20 ภาพที่ต้องเปลี่ยนชื่อ แต่ด้วย macOS ใหม่สคริปต์จะเปลี่ยนชื่อภาพ 2 ภาพและหยุดด้วยข้อความนี้

**error "Can’t get item 1 of {}." number -1728 from item 1 of {}**

นี่คือรหัส แต่ปัญหาเกิดขึ้นที่

set h to (item 1 of dimensions) --/ dpi_to_dpmm -- works out pixel height as mm

หากใครสามารถช่วยฉันขอขอบคุณมัน
