Vite dev server crashes when HttpClient receives non-200 code

[zip-fa]

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

v17

Description

Basically, it's a duplicate of angular/angular-cli#26192

But now it's here again with v19, zoneless and outputMode: 'server'.
Is this behaviour expected and not-an-issue on new setup?

Minimal Reproduction

ng serve

Exception or Error

No response

Your Environment

HttpErrorResponse

Anything else relevant?

No response

This is a known issue with zoneless, and it not limited to dev-servers.

In prod env, server will crash too? Is there any catch error mechanism that can be applied to not stop dev/prod app, but respond with 500 code?

[alan-agius4]

Yes, in the production environment, the server will crash because zone.js is not intercepting and handling unhandled errors and rejections.

Since the error is "unhandled," the request's lifecycle will continue in this scenario. For a potential workaround, please refer to angular/angular-cli#28405

Moving to the FW repo as following the convo in angular/angular-cli#28405 (comment) the FW should handle the errors.
