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 theprovideHttpClient
function call (e.g.provideHttpClient(withJsonpSupport())
) whenbootstrapApplication
is useddocs - 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.
