Request() API ignores headers in Android

Steps to reproduce

request({
    url: "https://example.com/",
    contentType: "application/json"
    headers: {
        // This will be ignored
        header1: "value1"
    },
    body: "{}"
})

request() API:

          * @public

          */

          export function renderMath(source: string, display: boolean): HTMLElement;

          

          /**

          * @public

          */

          export function renderResults(el: HTMLElement, text: string, result: SearchResult, offset?: number): void;

          

          /** @public */

          export function request(request: RequestParam): Promise<string>;

          

          /** @public */

          export interface RequestParam {

             /** @public */

             url: string;

             /** @public */

             method?: string;

             /** @public */

             contentType?: string;

             /** @public */

Expected result

headers will be sent to the target server.

Actual result

No headers other than Content-Type will be sent to the target server.

Environment

Operating system: Android
Obsidian version: v1.0.4

Additional information

It seems that contentType property replaces whole headers and we can’t set other than Content-Type header.

As a workaround, I used Fetch API:

developer.mozilla.org

Using Fetch - Web APIs | MDN

The Fetch API provides a JavaScript interface for accessing and manipulating parts of the HTTP pipeline, such as requests and responses. It also provides a global fetch() method that provides an easy, logical way to fetch resources asynchronously...

It seems to work both in Desktop and Mobile.
