[Posting test data, Invoice transaction fails - 422 Unprocessable Entity]

Following this guide https://developer.sage.com/accounting/quick-start/preparing-to-create-test-data/

 

Each failing request has a line in the Postman console TypeError: Cannot read property 'id' of undefined , which is happening on the lines in the test, so maybe that is not related to the 422 error. 

var setresp = pm.environment.get("invoice_metadata")

var indexCount = parseInt(pm.collectionVariables.get("indexcount")-1)

var invData = setresp[indexCount]

invData[2] = bodyData.contact.id

invData[3] = bodyData.id
