I have this code:

(defun send-raw-key-fun (str)
  (lexical-let ((str str))
    (lambda ()
      (interactive)
      (term-send-raw-string (read-kbd-macro str)))))

 (define-key term-raw-map (kbd "C-c c") (send-raw-key-fun "C-c"))

and it doesn’t work anymore with ansi-term. I’m not able to end the process inside.

Got error:

(wrong-type-argument stringp [3])

Does anyone know what to do to make this code work again?

    Looks like a bug (whether documentation or code) as read-kbd-macro still claims to return a string if possible, but nowadays it forcibly returns a vector. Please M-x report-emacs-bug to get that clarified.

    You could extract a string of characters from the vector:

    (mapconcat (lambda (event)
             (and (characterp event)
                  (char-to-string event)))
           (read-kbd-macro "C-c"))

    But if you look at the code for read-kbd-macro you’ll see that it calls this:

    (defun edmacro-parse-keys (string &optional _need-vector)
  (let ((result (kbd string)))
    (if (stringp result)
        (seq-into result 'vector)
      result)))

    Hence the string value you wanted is coming from kbd:

    (kbd "C-c") => "^C"

    There are of course arguments you can pass to kbd which won’t return a string, but that would always have been the case for your code, and presumably you’re not attempting to use any of those.
