Description

The type definition for HttpParamsOptions fromObject property only accepts string and string[]. If using immutable types, such as ReadonlyArray, you must create a new array unnecessarily to satisfy the type.

Describe the solution you'd like

Please change the type to the following (which is backwards compatible):

    fromObject?: {
        [param: string]: string | string[] | ReadonlyArray<string>;
    };
