200 now returned for missing assets instead of 404 #26917
Description
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
16
Description
I've updated a project from 16.2.11 to 17.1.0
When an attempt to load a missing asset is made the response is a 200 containing index.html instead of the expected 404.
This happens when using ng serve to run development locally, but i'm also seeing the same issue when deploying my production build to a staging server.
