Cannot optimize dependency: @pkg-name/package.json, present in client 'optimizeDeps.include'

[Badisi]

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

v19

Description

Trying to serve an angular application that has the following imports:

import authJsPkgJson from '@badisi/auth-js/package.json' with { type: 'json' };
import authVuePkgJson from '@badisi/auth-vue/package.json' with { type: 'json' };
import ngxAuthPkgJson from '@badisi/ngx-auth/package.json' with { type: 'json' };

will result in the following errors:

Cannot optimize dependency: @badisi/auth-js/package.json, present in client 'optimizeDeps.include'
Cannot optimize dependency: @badisi/auth-vue/package.json, present in client 'optimizeDeps.include'
Cannot optimize dependency: badisi/ngx-auth/package.json, present in client 'optimizeDeps.include'

Issue

Json file imports should not be considered "dependency" and be optimized.

Minimal Reproduction

Add any json file import in an angular application and run ng serve.

Exception or Error

Your Environment

Angular CLI       : 21.2.13
Angular           : 21.2.15
Node.js           : 24.14.1
Package Manager   : npm 11.16.0
Operating System  : darwin x64

Anything else relevant?

• There is no optimizeDeps.include defined in the app's angular.json file
• It doesn't show up on subsequent ng serve runs and does no harm, so it seems to be only warnings.
• Related issue: Failed to resolve dependency: angular:locale/data:en, present in client 'optimizeDeps.include #30491
