Description

Describe the problem

We had a support request with AGOL and they need the response headers, there is no way to get them from this package without patching the module (which we are attempting) When a status code 500/503 (non 200) error is returned the response headers are not exposed via the error object.

Describe the proposed solution

We are seeing if this will work (in my simulations it appeared to). Tweaking this code here seemed to do it.

https://github.com/Esri/arcgis-rest-js/blob/main/packages/arcgis-rest-request/src/request.ts#L424

            const { status, statusText, headers } = response;
            const { message, details } = jsonError.error;
            const formattedMessage = `${message}. ${
              details ? details.join(" ") : ""
            }`.trim();

            throw new ArcGISRequestError(
              formattedMessage,
              `HTTP ${status} ${statusText}`,
              {body: jsonError, headers: [...headers]},
              url,
              options
            );
          })
