Data path "" should NOT have additional properties(scripts) when adding external js to a non-application project

Question

Already updated my node and angular. When doing ng build I get error: Schema validation failed with the following errors:

Data path "" should NOT have additional properties(scripts).

generated project via:

ng n my-proj **-create-application=false**

angular.json :
