Troubles with porting a script to Gimp3

Thank you for your reply. I was trying to find where the error occurs in the code, but with no success. I have reverted some code to the one that was working in Gimp2. Here it is:

Code:

(let* ((off-x (car (gimp-drawable-get-offsets drawables)))
      (off-y (cadr (gimp-drawable-get-offsets drawables)))

With these changes in the script, posted earlier, I can start Gimp normally and run the script. But now I've got another error: "Error: in script, expected type: numeric for argument 1 to gimp-drawable-get-offsets". This error appears when the script executes gimp-
drawable-get-offsets for the first time. Now I can't understand why this error occurs. In Gimp console, if I run the following code:

Code:

(define (off-x x) (car (gimp-drawable-get-offsets x)))
(off-x 1)

I can get the correct result, when providing the function with correct drawable. However, I can't understand why I'm getting an error in the script.
