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

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:

docs.sentinel-hub.com

Examples for S2L2A

Use these CURL and Postman examples to access atmospherically corrected Sentinel-2 L2A data with Sentinel Hub API.

And it works for me.

Sure, here is the payload:

def get_payload(strt_dt, end_dt, resp_type, evalscript):

    payload = {

            "input":{

                "bounds":{

                                }

                            ]

                        }, "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).
