How to replace buildTarget in angular 17 instead of browserTarget in version 16?

Question

I get error when I was run angular like below:

   Error: Schema validation failed with the following errors:
  Data path "" must have required property 'browserTarget'.

because I am using angular Cli version 17 then my angular.json it has some difference from Angular 16 So I changed buildTarget to browserTarget but I got this error.

This version of CLI is only compatible with Angular versions ^16.0.0,

but Angular version 17.0.8 was found instead.

This is my angular.json

Answer 1

After few hours I find out the answer to fix this bug I am just use these two commands:

ng update @angular/cdk
ng update @angular/core

and my project run with out any issue.

Answer 2

I also faced the same issue while running the npm start

Error: Schema validation failed with the following errors: Data path "" must have required property 'browserTarget'.

Then tried to build the project using ng build, and now I got

This version of CLI is only compatible with Angular versions ^16.0.0, but Angular version 17.0.8 was found instead.

Please visit the link below to find instructions on how to update Angular. https://update.angular.io/ Blockquote

Issue was @angular-devkit/build-angular:^16.2.11 in package.json

Solution: Update the above dependency with the latest version using ng update @angular-devkit/build-angular
