JSONP support in HttpClient configuration

Angular produces this error when you attempt a JSONP request without providing the necessary support for it in the HttpClient configuration. To enable JSONP support, you can do one of the following:

  • add the withJsonpSupport() as an argument during the provideHttpClient function call (e.g. provideHttpClient(withJsonpSupport())) when bootstrapApplication is used
  • import the HttpClientJsonpModule in your root AppModule, when NgModule-based bootstrap is used.## Debugging the error Make sure that the JSONP support is added into your application either by calling the withJsonpSupport function (when provideHttpClient is used) or importing the HttpClientJsonpModule module as described above.
