How to interact with JHipster context in blueprints

Question

I'm new in JHipster, but I already have a task - to make a blueprint for an Angular client side change with jhipster-generator (by npx jhipster generate-blueprint)

What I did:

1. Generated non-local blueprint
2. Copy angular folder from node_modules/generator-jhipster. So, structure is follow:

structure of blueprint project

3. Injected a new markup

4. Created "npm link"

5. Generate project connected to this blueprint.

Package-json of blueprint: package.json of blueprint

1. I edited template file of Angular, added this to files in generator.mjs:

   get [AngularGenerator.WRITING]() {
       return this.asWritingTaskGroup({
         ...super.writing,
         async writingTemplateTask({ application }) {
           await this.writeFiles({
             sections: {
               files: [{ templates: ['/src/main/webapp/app/entities/_entityFolder/list/_entityFile.component.html.ejs'] }],
             },
             context: application,
           });
     },
   });
   

   }

My problem:

error

How to inject in my project Jhipster context? All variables, as I understand it, can be taken from the JHipster context. Also, I want to add new functionality, that is, also expand the context. How to interact with the context? Thanks for the answer
