Character '&' not supported in process description for r.mapcalc" #82

Closed LeGuide closed 3 years ago

LeGuide commented 4 years ago

When using the & operator in r.mapcalc, the process chain is not valid. Example:

{
  "version": "1",
  "list": [
    {
      "id": "r.mapcalc",
      "module": "r.mapcalc",
      "comment": "test the && operator",
      "inputs": [
        {
          "param": "expression",
          "value": "test_raster = if(elev_srtm_30m>10.0 && slope>1.0)"
        }
      ]
    }
  ]
}

Both process_chain_validation_sync as well as processing_async_export result in the error:

It seems to happen here:
