Hello, I'm trying to upload assets using the app store connect api, I have successfully created a screenshot set, and created a screenshot reservation and got back the following response: "data": { "type": "appScreenshots", "id": "...", "attributes": { "fileSize": 4833, "fileName": "Untitled.png", "sourceFileChecksum": null, "imageAsset": null, "assetToken": "...", "assetType": "SCREENSHOT", "uploadOperations": [ { "method": "PUT", "url": "...", "length": 4833, "offset": 0, "requestHeaders": [ { "name": "Content-Type", "value": "image/png" } ] } ], "assetDeliveryState": { "errors": [], "warnings": null, "state": "AWAITING_UPLOAD" } }, "links": { "self": "..." } }, "links": { "self": "https://api.appstoreconnect.apple.com/v1/appScreenshots" } } The documentation states that I should use the "UploadOperations" to upload the image using the "put" method and using the url provided in the response under "UploadOperations", however I am not sure what to send in the body of the put request. I have tried the following but it is returning an empty response: headers = { "name": "Content-Type", "value": "image/png" } urlUpload = response.json()["data"]["attributes"]["uploadOperations"][0]["url"] response = requests.put(urlUploadTo,image=image, headers=headers) What exactly am I doing wrong here? Is there something I'm missing? The following link is the link to the documentation explaining how to upload assets.
