message becomes undefined if @ is included in the body

[pa-uyama]

[vite] Internal server error: Cannot read property 'message' of undefined    

Even forceStringify: true had no effect.
The same goes for backslash escapes.

plugins: [
  VueI18n({
    forceStringify: true,
    include: [resolve(__dirname, 'locales/*')],
  }),
],

locales/en.yaml

test:
  error: a@a
  error2: a\@a

Is this a bug?

It seems to be the same problem as here.
Sorry.
