Language 'de-de' is not supported by the platform

[Lokesh]

For my google action, I have used i18n and have en-US and de-DE in models.
Once I build the project using jovo build and IMPORT ZIP folders in the platform -> google action -> dialogflow to Export and Import in Dialogflow, I am getting Language ‘de-de’ is not supported by the platform.
I have also specified languages to English - en and German - de in Languages tab of Dialogflow.
any kind of help is appreciable

Hey @Lokesh

This might be the answer to your question:

[Docs] project.js - Project Configuration | Jovo Framework

/models
en.json
de.json

project.js

alexaSkill: {
    nlu: {
      name: 'alexa',
      lang: {
        en: [
          'en-US',
          '...',
        ],
        de: [
          'de-DE'
         ]
      }
    }
  },

Hi ALexSwe,

That did not help, still getting the same error.
Is it something related to Dialogflow

I got the same issue and this actually fixed it for me!
I just renamed en-US.json and de-DE.json to en.json and de.json.

As an alternative, I recommend this audio to text converter. It supports German and other languages.
