API Workflow parameters

[hugo-codestack]

Hi all,

I have a VM running Farmvibes and the API exposed to be consumed by our product but I have some issues regarding the parameters of the following workflow:

data_processing/index/index

This is the error message

{
  "id": null,
  "location": null,
  "message": "Unable to run workflow with provided parameters. Workflow source raster expects inputs of type <class 'vibe_core.data.rasters.Raster'>, found incompatible types: vibe_core.data.core_types.DataVibe"
}

For this I sent this parameters:

{
  "name": "test",
  "workflow": "data_processing/index/index",
  "parameters": {
    "index": "ndvi"
  },
  "user_input": {
    "start_date": "2021-02-02",
    "end_date": "2021-08-02",
    "geojson": {
      "type": "Feature",
      "properties": {},
      "geometry": {
        "type": "Polygon",
        "coordinates": [
          [
            [
              -121.802855,
              38.800393
            ],
            [
              -121.803064,
              38.793833
            ],
            [
              -121.797972,
              38.793696
            ],
            [
              -121.798158,
              38.800376
            ],
            [
              -121.802855,
              38.800393
            ]
          ]
        ]
      }
    }
  }
}

Can you please help me with this? I want to understand what parameters the workflow expects.

Hi, @hugo-codestack. Thanks for using FarmVibes.AI and raising this question.

You are missing a workflow that downloads a Raster, over which the NDVI will be computed. The workflow data_processing/index/index expects a Raster object, which comes from a few of our data_ingestion workflows (e.g., Sentinel-2, LandSat, etc). You are passing as input a DataVibe with the geometry and time range, but these should first be used to download the raster.

The following examples and documentation will probably help you:

• Spectral Indices notebook: an example of how to combine a download operation (in this case, Sentinel-2 download) with the data_processing/index/index workflow to compute several indices. Specifically, the indices.yaml file in this folder shows you a custom workflow that you can adapt for your scenario.
• Building custom workflow documentation pages with more details on how to build a custom workflow and combine multiple workflows in FarmVibes.AI.

Please, let me know if you are able to run your workflow.
