Using ExtractData in ArcGIS API for Javascript?

Question

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',
 description:
 'Clip and download soil type, home site and forest layers.',
 },
 },
 });

• NettaB: 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/…
• Cyril Cherian: @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 }, ]),
• NettaB: That's awesome, please add your solution as an answer - for future generations :)
• Daniel Benedik: can you share your parcelURL please?

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