Error on +snippet/edit

[Janfel]

What actually happened?
Calling +snippet/edit interactively on some snippets throws an error. Backtrace below.

Debugger entered--Lisp error: (wrong-type-argument arrayp nil)

  (progn (aref template 6))

  (let* ((major-mode (if (eq major-mode 'snippet-mode) (intern (file-name-base (directory-file-name default-directory))) major-mode)) (template (yas--get-template-by-uuid major-mode template-uuid)) (template-path (progn (progn (aref template 6))))) (if (file-in-directory-p template-path +snippets-dir) (find-file template-path) (let ((buf (get-buffer-create (format "*%s*" (file-name-nondirectory template-path))))) (save-current-buffer (set-buffer (switch-to-buffer buf)) (insert-file-contents template-path) (snippet-mode) (setq default-directory (expand-file-name (file-name-nondirectory template-path) (expand-file-name (symbol-name major-mode) +snippets-dir)))))))

  apply(explain-pause--wrap-call-interactively # (+snippets/edit nil nil))
  call-interactively(+snippets/edit nil nil)
  command-execute(+snippets/edit)

Steps to reproduce:

1. Open a new emacs-lisp-mode buffer.
2. Call +snippets/edit (e.g. C-c & C-v).
3. Choose snippet yn (for y-or-n-p).

As of 5d5d94d this issue should be resolved. Let me know if that isn't the case and I'll reopen it. Thanks for bringing it to my attention!

Unfortunately, the issue is not resolved for me. I'm seeing the exact same error, but I'm not using doom-snippets.

(wrong-type-argument arrayp nil)
  (aref nil 6)
  (progn (aref template 6))
  (progn (progn (aref template 6)))
  (let* ((major-mode (if (eq major-mode 'snippet-mode) (intern (file-name-base (directory-file-name default-directory))) major-mode)) (template (yas--get-template-by-uuid major-mode template-uuid)) (template-path (progn (progn (aref template 6))))) (if (file-in-directory-p template-path +snippets-dir) (find-file template-path) (let ((buf (get-buffer-create (format "*%s*" (file-name-nondirectory template-path))))) (save-current-buffer (set-buffer (switch-to-buffer buf)) (insert-file-contents template-path) (snippet-mode) (setq default-directory (expand-file-name (file-name-nondirectory template-path) (expand-file-name (symbol-name major-mode) +snippets-dir)))))))

@czikus 523ced6 should fix the issue.

@hlissner The error is indeed gone, but now instead of a snippet buffer, I'm only seeing a message "Couldn’t find a snippet with uuid nil".
