Error when evaluating SSR module ./server.mjs: Cannot split a chunk that has already been edited (0:76 – "import.meta")

Unpack testing-app.zip and inspect src/server.ts, especially line 20, then reproduce the failure with npx ng serve. Trace the SSR transformation shown in the Vite stack and compare behavior with that line enabled or commented; done means the minimal reproduction serves successfully with the intended server code intact.

Command

serve

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

Description

I just created an Angular application and

• Added Hono and configured it for SSR
• Added Drizzle ORM
• Added Better Auth

I configured every library following their documentation, but when I run npx ng serve I get this error :

Commenting line 20 of src/server.ts, then re-running the serve command makes it work.
