config.json file cannot be found in Angular v20

I have just updated my Angular app from version 19 to v 20. The updated seemed to work fine except the JSON files in my assets folder no longer. I have a config.json file in the assets folder which is deployed to the server as part of the package. During the DevOps I use a file transformation tasks to make changes just before the new files are uploaded.

The error is:

The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
​

However:

1. The config.json is present in the live directory. I can see it there when I examine the live files.
2. It works 100% fine when running Angular 19 (I rolled back the changes to test this and with v19 all works fine).
3. Also when I insert the URL of the file in the browser, it cannot be found with v20 running. But with v19, and HTTP get to the file works.

Am I missing something simple here, or is there a change in v20 that I am not aware of?
