cypress how to use JSON response property in another request

Question

I seem to be having issues interacting with the response body from cy.request. I have two API calls that are both working singularly. I would like to send an id from the response array of the first call to be used by the second call.

Cypress.Commands.add('POST_and_PATCH_Order',() => {
    cy.fixture('orderEntry.json').then((fileBody)=>{

      cy.request({
          method:'POST',
          url:'/api/OrderEntry',
          json: true,
          body: fileBody
      })
    })
    .then(response => {     

        return new Promise(resolve => {
            const target = response.body;
            resolve(target)
        })
    })
})

Then testing with

it("An order may be set to delivered", ()=>{

  cy.POST_and_PATCH_Order().then(order =>{
      const OrderId_val = order['OrderId'];
      cy.request({
        method:'PATCH',
        url:'/api/OrderManager/StatusDelivered',
        json: true,
        body: {
          "OrderId": OrderId_val,
          "ActualPickupDate": "2020-06-08T15:34:20.035Z",
          "ActualDeliveryDate": "2020-06-08T15:34:20.035Z",
          "DeliveryReceiptName": "string"
        }
      })
  })
})

sending OrderId_val as above gets a 404 response with the request body not providing a value for OrderId. Sending order as OrderId results in the entire response header being sent as the OrderId (Body: {"OrderId":[{"OrderId":3588901,"OrderType":"Order","Uuid":"1591821576913"}],"ActualPickupDate":"2020-06-08T15:34:20.035Z","ActualDeliveryDate":"2020-06-08T15:34:20.035Z","DeliveryReceiptName":"string"})

I have tried interacting further with the response.body in command.js & in the test but encounter NullReferenceException outcomes. Would be grateful for any help accessing the OrderId value from the POST response to be used in the subsequent PATCH call.

What does fileBody print? Is it [{"OrderId":3588901,"OrderType":"Order","Uuid":"1591821576913"}], if so you should read order[0].OrderId — Sree.Bh
I didn't notice there was a comment already. that is exactly what I needed (order[0].OrderId in the test constant that is sent to the second request body). thanks a bunch, I was not finding a ton of examples working with response body that lined up with this scenario. — knr
new to Stack Overflow mechanics, but if you push that through as answer I can mark it as a successful answer to my question. thanks again, Sree.Bh! — knr

Your fileBody has the data in array format:[{"OrderId":3588901,"OrderType":"Order","Uuid":"1591821576913"}]

You should read it as order[0].OrderId.
