Language switch does not appear

[JuliusStoll]

Situation:

So, I am trying to set up my very basic academic page in two languages.
Therefore, I have followed all guidelines so my files read the following:

So the language section in the Website/config/_default/config.yaml looks like this:

`defaultContentLanguage: en

hasCJKLanguage: false

defaultContentLanguageInSubdir: false

removePathAccents: true
`

My config/_default/languages.yaml file reads like this:

`Default language
en:
languageCode: en-us
contentDir: content/en

de:
languageCode: de
contentDir: content/de
title: Website Title in German
params:
description: Website Description in German`

I've added a i18n folder with the standard de.yaml language file.

In addition to the Website/config/_default/menus.yaml file I have added a Website/config/_default/menus.de.yaml file (on the wowchemy instructions, it talks about menu.toml files? Is that a problem?)

Regarding content, I have put the content in two language directories, Website/content/de/ and Website/content/en/ where all subsequent folders have the same structure/name and only differ in their content language.

Problem: My website still only displays the english default version, there is no button to switch versions to the German one. What am I doing wrong?

Thank you guys for your help! So far all went perfectly well, thus I am curious where my mistake is at.

Best,

Julius

Have you enabled the language chooser in params.yaml?

main_menu:
  show_translations: true
  show_language: true  # If you wish to display the current language name
footer:
  show_translations: true

Thanks for helping me out, Geo. I probably came closer to the true problem.

Turns out, Netlify failed to produce the last couple of builds. (Sorry I didn't check that earlier)
The first build failed when introducing the language.yaml file. The Error was:

Since I've recognised some of the translation from the menus.de.yaml file, I've tried to get it to build without the menus.de.yaml translation file at all, but it produced a similar error:

Do you have an idea what the problem might be?
Many thanks in advance!
