SSR Setup: Failed to add FTL resources to the bundle

[JLouisa]

Describe the bug:
I started a new project and choose a ssr build with postgres (see image):
I put in my postgres local test db link in config and start the project and I keep getting the error:
"Error: Message("Failed to add FTL resources to the bundle")" (see image 2)
I cannot find any info on how to fix this.

Your Example Website or App:
New app with "Loco New"

Steps to Reproduce the Bug or Issue:
Start a new project with "Loco new"
Put in an App Name.
For "What would you like to build? " choose "Saas App with server side rendering".
For "Select a DB Provider ›" choose "Postgres"
For "Select your background worker type ›" choose "Async (in-process tokio async tasks)"
Put in a valid postgres link in config
Use "cargo loco start" to start the server

Expected behavior:
Server start up and you can go to scaffold homepage/ fallback page.

Platform:
Ubuntu 25

Additional context:
I don't get this issue with I choose client side rendering, only ssr.

This is what I found out (probably not 100% accurate):
The ArcLoader in fluent-templates 0.13 scans the i18n directory for both subdirectories (treated as locales) and root-level .ftl files whose stem is a valid BCP 47 language tag. The stem shared is a valid 6-letter primary language subtag, so shared.ftl was being registered as a locale named shared. When building that locale's bundle, fluent-templates added shared.ftl twice — once as the explicit shared resource, once as the locale's own content — causing a duplicate something entry and the bundle error.

The fix was to move shared.ftl one level up to assets/shared.ftl so it's outside the scanned assets/i18n/ directory, and update the I18N_SHARED constant in src/initializers/view_engine.rs:12 to point to the new path.

So now it starts the server and loads the fallback page. It's a work around not a fix.
