# Error: error:badreq
Bad Request Configuration

    Http request configuration must be an object.  Received: {0}

## Description

This error occurs when the request configuration parameter passed to the `$http` service is not an object. `$http` expects a single parameter, the request configuration object, but received a parameter that was not an object. The error message should provide additional context such as the actual value of the parameter that was received. If you passed a string parameter, perhaps you meant to call one of the shorthand methods on `$http` such as `$http.get(…)`, etc.

To resolve this error, make sure you pass a valid request configuration object to `$http`.

For more information, see the `$http` service API documentation.
