Describe the feature

In case of error, it is important to know the reason of failure. In our use case, we need to display the reason for failure to the user. The backend sends the reason for failure in the error message, but pdk internally returns standard static message : "Response returned an error code". Is there a way to get the actual error message that the backend returns? If not, we should update this to pass back the actual error message sent by the backend.

Code:

protected async request(context: RequestOpts, initOverrides?: RequestInit | InitOverrideFunction): Promise<Response> {
        const { url, init } = await this.createFetchParams(context, initOverrides);
        const response = await this.fetchApi(url, init);
        if (response && (response.status >= 200 && response.status < 300)) {
            return response;
        }
        throw new ResponseError(response, 'Response returned an error code');
    }

export class ResponseError extends Error {
    override name: "ResponseError" = "ResponseError";
    constructor(public response: Response, msg?: string) {
        super(msg);
    }
}

Use Case

There's a UI screen that can fail for multiple reason. We need to tell the user the exact reason for the failure. We send the exact reason from backend but there's no way to get it in frontend with the current code.

Proposed Solution

response is already present in the code, just need to propagate the message in the final function.
