IDE Error Report (v4.7.0) - Handling null values for translations

[antoine-malliarakis-pigment]

Additional information

We have a translation file resource containing null values (which is expected and works well for our runtime process, it essentially means that we're explicitly not translating those).

Exception trace

An error occurred while processing translation files.
Config: MODULARIZED_LOCALE => JSON (*.json)
Path: <>
Please check examples at https://github.com/marhali/easy-i18n before reporting an issue!
