Hi Kartheek, There seems to be a bug in the way we publish our Angular module and hence the dependency injection does not work properly. I am already on it, Please follow it along here for the update [https://github.com/elastic/apm-agent-rum-js/issues/437](https://github.com/elastic/apm-agent-rum-js/issues/437) Thanks, Vignesh ---

@vigneshshanmugam thank you for your response. One question I have is do you recommend using this version of angular-rum in production environment or would be recommend us waiting for a stable version? ---

Hi Kartheek, We have released a new version of `@elastic/apm-rum-angular@0.2.1` which should fix the above issue. The `ApmService` provider would need explicit injection to make it work with Angular CLI. Please refer to the doc - [https://www.elastic.co/guide/en/apm/agent/rum-js/master/angular-integration.html](https://www.elastic.co/guide/en/apm/agent/rum-js/master/angular-integration.html) You can use it in production right now, we did not release a major version `1.x` since we might explore API changes in the future if required. Let us know how it works out for you. Thanks, Vignesh ---
