Error: search-failed ",tkk:'"

[jumper047]

Error appears when I trying to translate someghing.
There is debugger output:

Debugger entered--Lisp error: (search-failed ",tkk:'")
  search-forward(",tkk:'")

I’m having the same issue. Apparently the tkk doesn’t always appear on the page anymore. This is very crude, but seems to work:

(defun google-translate--search-tkk ()
  "Get the Token-Key from the page buffer."
  (let (downloaded)
    (setq downloaded (shell-command-to-string "curl -s --user-agent 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_2) AppleWebKit/600.3.18 (KHTML, like Gecko) Version/8.0.3 Safari/600.3.18' 'https://translate.google.com' | sed 's/,/\\n,/g' | grep ',tkk'"))
    (print downloaded)
    (with-temp-buffer (insert downloaded)
		      (goto-char 0)
		      (re-search-forward ",tkk:'\\([0-9]+\\)\\.\\([0-9]+\\)")
		      (list (string-to-number (match-string 1))
			    (string-to-number (match-string 2))))))

Sometimes it appears not to work on the first time, but on the second one it does work. I have no idea why.

I also have same issue.
There is some discussion in #52
I found that following way also works Ok:

(defun google-translate--search-tkk ()
  "Search TKK."
  (list 430675 2721866130))

[rileyrg]

(defun google-translate--search-tkk ()
"Search TKK."
(list 430675 2721866130))

I was messing around for ages and finally this form works for using straight/use-package. The require in the :init was the key. Zero clues as to why.

     (use-package google-translate
       :demand t
       :init
            (require 'google-translate)

       :functions (my-google-translate-at-point google-translate--search-tkk)
       :custom
       (google-translate-backend-method 'curl)
       :config
       (defun google-translate--search-tkk () "Search TKK." (list 430675 2721866130))
       (defun my-google-translate-at-point()
         "reverse translate if prefix"
         (interactive)
         (if current-prefix-arg
             (google-translate-at-point)
           (google-translate-at-point-reverse)))
       :bind
       ("C-t". my-google-translate-at-point))

Same issue here. 😕

@atykhonov @stardiviner Any idea? Thanks!

[stardiviner]

@jcs090218 As upper mentioned #52 problem. For now, there is no prefect solution. You can use upper temporary solution. Seems Google Translate return different values on different machines and requests.

[parjanya]

they changed their API: https://github.com/Boudewijn26/gTTS-token/blob/master/docs/november-2020-translate-changes.md

Check out this old issue #52 for more information.
