Tabulation not working in CSS part of vue-mode

[M-Gregoire]

I get an error each time I try to use in the CSS part of a vue file.
Error : vue-mmm-indent-line-narrowed: Symbol’s function definition is void: nil

mmm-mode-0.5.7
vue-mode-20180516.312

Thank you

It's possible that your emacs configuration is causing something to fail. Could you try to reproduce it with emacs -Q, and post a snippet which causes the failure if you can reproduce it there?

Thank you for your quick answer ! I've managed to reduce the problem to a minimal example :
init.el

; Let's use melpa !
(require 'package)
(add-to-list 'package-archives
             '("melpa" . "https://melpa.org/packages/"))

; We start the package system
(package-initialize)

; Refreshing the package list each time it's loaded
(unless package-archive-contents
  (package-refresh-contents))

; Quick function to download and activate package
(defun ue-ensure-installed (packages)
  (dolist (package packages)
    (unless (package-installed-p package)
      (package-install package))))

; Vue.js
(ue-ensure-installed '(vue-mode))

test.vue

<template>
</template>

<script>
</script>

<style>
  .example
    text-align center
</style>

If you try to indent the .example you will get the error.

I tried to delete my .emacs.d folder and just put the init file above and I do get the indenting error.

Anyone found a solution for this? I'm getting the same problem.
