How to use locales with hyphen?

🆘 Support
1

Hello, for a project I need to use nl-BE as a language.
in i18n.js i have

	clickCta: {
		en: 'Click here',
		'nl-BE': 'Klik hier',
	},

I do assume this is correct as I do not get any error.

I have ensured to update the language bar… but the moment I click nl-BE it displays a 404, with no further errors. All other languages are working. I am 100% sure that all languages / posts are published.

In vercel I do see an error:

Ouch! The query has some errors!
[
  {
    message: 'Parse error on "-" (error) at [1, 29]',
    locations: [ [Object] ]
  }
]
> Build error occurred

Hey @ZeroEqualsZero

Are you getting that error when submitting a graphQL query to Dato? If so, can you send us the query you are sending?
