I cannot find any sample using ExtractData API.

I am trying to extract data from hosted feature layers using ExtractData JS API (not widget). The job that I submit fail with the following message.

Error: [{"type":"esriJobMessageTypeError","description":"ERROR 000735: inputLayers: Value is required"},{"type":"esriJobMessageTypeError","description":"Failed."}]

Following is part of the request. The 'instance' object has root url and credentials. All layers are accessible and also I had made them public for testing purpose. I have spend lot of time trying to resolve this issue. There is no other meaningful information coming out of GP Service.

const job = await instance.get('/submitJob', {
        params: {
          inputLayers: [
             { url: soilURL, serviceToken: user.creds.token },
             { url: forestURL, serviceToken: user.creds.token },
             { url: homesiteURL, serviceToken: user.creds.token},

          extent: {
            url: parcelURL, 
            serviceToken: user.creds.token,
            filter: parcelFilter,
          clip: true,
          dataFormat: 'FILEGEODATABASE ',
          outSR: 102100,
          outputName: {
            title: 'ACT 319 clip data',
            tag: 'clip data',
            snippet: 'clip data',
              'Clip and download soil type, home site and forest layers.',
  • I know it sounds extreme, but most of ESRI's doc uses double quotes for attribute names. Try replacing url: soilURL with "url": soilURLetc. based on developers.arcgis.com/rest/analysis/api-reference/… – NettaB Sep 13 '19 at 10:23

    @NettaB Thank you for your response. We were able to finally resolve the issue by using JSON.stringify to convert the parameter to string inputLayers: JSON.stringify([ { url: soilURL, serviceToken: user.creds.token }, ]), – Cyril Cherian Sep 14 '19 at 4:08
  • That's awesome, please add your solution as an answer - for future generations :) – NettaB Sep 14 '19 at 11:50

We resolved the issue by JSON.stringfy() the parameter. inputLayers: JSON.stringify([ { url: soilURL, serviceToken: user.creds.token }, ]),
