  • Searched for relevant instructions on our Discord server
  • Searched the issues of the repository you are working in to make sure one was not already filed

Summary

If the translation of text hasn't be added by a translator, the resulting value will be empty. In this case, the value should instead be the english value so that the key can be used by i18next while indicating there needs to be a translation of the text.

Motivation

When the app is in a non-english locale, there needs to be a translation provided and if not, a way to signal the translation needs to be added. This signal can be the text in english.

Possible Alternatives

Nothing shows up so debugging is more difficult.

Additional Context

pull_gsheets_translations_mvp.py needs to be updated with a conditional. If the translatedValue is empty, replace with the english value.
