Issue with Retrieving NDVI Data from PlanetScope

Hi,

We have started testing PlanetScope, but we are unable to retrieve NDVI data for the selected area.

In My Collections, we created a Collection with ID, and we added a Subscription to it. The PlanetScope data was successfully loaded—we can see and download it via the web application.

However, when we try to generate NDVI using the API endpoint https://services.sentinel-hub.com/api/v1/process, we do not receive any data. The endpoint returns null.

Request:

      ]
   },

      "responses":[

            }
         }
      ]
   },
   "evalscript":"//VERSION=3\nfunction setup() {\n  return {\n    input: [\"nir\", \"red\", \"dataMask\"],\n    output: {\n\t  bands: 1,\n      sampleType: \"FLOAT32\"\n\t},\n  };\n}\n\nfunction evaluatePixel(sample) {\n  if (sample.dataMask == 0) {\n    return [ NaN ];\n  }\n  return [(sample.nir - sample.red) / (sample.nir + sample.red)];\n}\n"
}

In the web application, we noticed that the data is in UTM, so we also tried modifying the request and querying in UTM, but the result was still null.

We would really appreciate your advice and assistance.
