Line 25 in ecebb90

export class RetryHandler implements Middleware {

Let us know if you have any additional comments or questions.

Any idea why it does not include this header in actual request but it shows in console? @baywet

  public async execute(
    url: string,
    reqInit: RequestInit,
    reqOptions?: Record<string, RequestOption>
  ): Promise<FetchResponse> {
    return this.executeInternal(url, reqInit as FetchRequestInit);
  }

  private async executeInternal(
    url: string,
    reqInit: FetchRequestInit
  ): Promise<Response> {
    setRequestHeader(reqInit as FetchRequestInit, 'Test', `Test`);

    console.log(reqInit as RequestInit);

    const res = await this.next?.execute(url, reqInit as RequestInit);
    if (!res) {
      throw new Error('Response is undefined');
    }

    return res;
  }

Can you check what versions of the packages are actually installed and upgrade to the latest please? There used to be a a similar bug we fixed in #1358
