Getting "Language file not found." error when trying to change the Timezone in the admin settings

[Hoid]

Describe the bug

Getting an error dialog when trying to save anything on the Settings -> Interface page. As a result of this bug, I cannot change the timezone setting in the app from Shanghai to anything else.

To Reproduce

Steps to reproduce the behavior:

1. Go to Settings -> Interface on the admin account
2. Change one of the settings, such as the Timezone or Default avatar, and click Save. I was originally trying to change the Timezone from Shanghai to New York. You can also just not change anything and click Save and it will still show the error.
3. See error dialog that says Language file not found.

Expected behavior

No error and the Timezone is able to be updated

Screenshots

Platform

• Device: Laptop
• OS: MacOS Tahoe 26.1
• Browser and version: Zen browser (fork of Firefox), 1.17.4b (Firefox 144.0.2)
• Version: I believe I have v1.7.0, but the version in the charts/Chart.yaml file is v1.0.7. I've built a new image from the latest main branch, however.
• Also, I'm using the default in-memory sqlite database. I plan to change to postgres soon but figured that might be relevant information.

@Hoid The cause of this issue is most likely unrelated to time zones and instead pertains to language settings. Although I haven't been able to reproduce the problem, I can speculate that it may stem from your system's language setting currently being empty. When empty, the default language defaults to English. Consequently, while the frontend interface displays English, the request submitted actually carries an empty value. This discrepancy triggers the error.
If this is the case, you could try switching to a different language, saving your changes, then reverting to English and saving again.
Please let me know if this resolves the issue. Thanks.

Hi!

You were correct, somehow the language file wasn't loaded or created at app startup time, so changing the language to something else then back to English allowed me to change the Timezone. Is this something that can be fixed in the app initialization, so that the language file is always created and we won't get this error each time someone creates a new instance? It would reduce the number of bugs created for this issue and reduce the amount of times people hit this bug and don't know what to do and just give up on Apache Answer.

@Hoid Sure. We shall fix this issue to prevent it from affecting new users. The occurrence of this issue may be related to the installation process.
