Getting Format application/json does not support sample type AUTO error

1

We have a lot of applications working on the /api/v1/process endpoint, they kept working for weeks and suddenly we noticed they have stopped working now. When I debugged the code:

res = requests.request("POST", url, headers=headers, data = json.dumps(payload), timeout=10)

I get the following error when I print res.content:

{"error":{"status":400,"reason":"Bad Request","message":"Format application/json does not support sample type AUTO.","code":"RENDERER_EXCEPTION"}}

Can you share the process API request that you do?

Sure, here it is:

url = "https://services.sentinel-hub.com/api/v1/process"

headers = {
  'Accept': '*/*',
  'Content-Type': 'application/json',
  'Authorization': f'Bearer {token["access_token"]}',
  'Origin': 'https://apps.sentinel-hub.com',
  'Connection': 'keep-alive',
  'TE': 'Trailers'
}

script_str_json = """
//VERSION=3

function setup() {
  return {
    input: ["B02", "B03", "B04"],
    mosaicking: Mosaicking.ORBIT,
    output: { id:"default", bands: 3}
  }
}

function updateOutputMetadata(scenes, inputMetadata, outputMetadata) {
  outputMetadata.userData = { "metadata":  JSON.stringify(scenes) }
}

function evaluatePixel(samples) {
  return [ 2.5*samples[0].B04, 2.5*samples[0].B03, 2.5*samples[0].B02 ]
}
"""

payload = get_payload(strt_dt, end_dt, "application/json", script_str_json)

I use this evalscript i.e. script_str_json to get the metadata and extract the correct date of the file.

Can you send the request part as well, you’ve just submitted the evalscript.

I have used your evalscript in a combination with request described in this part:

And it works for me.

Sure, here is the payload:

def get_payload(strt_dt, end_dt, resp_type, evalscript):
    payload = {
            "input":{
                "bounds":{
                "geometry":{  
                    "type": "Polygon",  
                    "coordinates": COORDINATES
                    },
                    "properties":{
                    "crs":"http://www.opengis.net/def/crs/EPSG/0/32719"}},
                    # "crs": "http://www.opengis.net/def/crs/OGC/1.3/CRS84"}},
                    "data":[{
                        "dataFilter":{
                        "timeRange":{
                            "from":strt_dt,
                            "to":end_dt
                            },
                            "maxCloudCoverage":100,
                            "previewMode":"EXTENDED_PREVIEW"},
                            "processing":{"upsampling":"BICUBIC"},
                            "type":TYPE}]},
                        "output":{"resx":10,"resy":10,
                        "responses": [
                                {
                                    "identifier": "default",
                                    "format": {
                                        "type": resp_type
                                    }
                                }
                            ]
                        }, "evalscript": evalscript 

            }

    return payload

payload = get_payload(strt_dt, end_dt, "application/json", script_str_json)

res = requests.request("POST", url, headers=headers, data = json.dumps(payload), timeout=10)

I am trying to reproduce your error, but I am not able to. It works for me.

Can you send an actual example of the request, with filled values (you’ve sent a proto-request).
