[BUG] Getting “inject() must be called from an injection context” after upgrading to Angular 11

Description

After having generated an API-client under the org.openapi.generator:5.0.0 using the org.springdoc.openapi-gradle-plugin:1.3.0, my web application crashes, giving me the following error:

main.ts:12 Error: inject() must be called from an injection context

Generation Details

I am using the openapi-generator-gradle-plugin:

openApiGenerate {
    generatorName = 'typescript-angular'
    inputSpec = swaggerFilePath
    outputDir = apiClientOutputDir
    configOptions = [
            npmName   : 'meditation-rest-client',  // Api-client name
            npmVersion: '0.0.1',                   // Api-client version
            ngVersion : '11.0.6'
    ]
}

Steps to reproduce

1. Build an API-Client from a Spring Boot Application
2. Reference the API-Client in your Angular 11 Web-Application
3. ng serve
4. Find the error in your console
