call web integration to write to datastore

HI,

I am trying to create a process with 2 nodes: call an integration + write to db

The integration returns a Result.body - this variable is available in the next node....Example of body (json)

body (Dictionary)

• orders (List of Dictionary - 272 items)

• Dictionary
  • orderNumber5105251(Number (Integer))
  • operatingUnitId1030(Number (Integer))
  • operatingUnitName"GEMSAM_OU_LNR_GEMS_LUNAR"(Text)
  • contractAmount4600(Number (Integer))
  • status"B"(Text)
  • purchaseOrderNumber"1681345522"(Text)
  • customerNumber"131441"(Text)
  • customerName"WOODLAND MEMORIAL HOSPITAL"(Text)
  • deleted0(Number (Integer))
• ....
•  
  • bookedDate11/1/2021 8:23 PM GMT+00:00(Date and Time)
  • initDate11/1/2021 7:59 PM GMT+00:00(Date and Time)
  • customerContractAmount4600(Number (Integer))
• Dictionary
  • orderNumber5104156(Number (Integer))
  • operatingUnitId1030(Number (Integer))
  • customerNumber"5455"(Text)
  • customerName"SOUND"(Text)
  • .....

I tried to directly access the body.orders[0] for example at the write to db node but I am getting a "failed to index error"

I also tried to save the 1st item into a process variable in the call integration node, but I am getting the same error. 

Any ideas? 

I also followed the SpaceX sample with launches/rockets - which maps a rest api to a record store - I got this to work with my specific data type.

but these are not saved in any DB table....is there a way to save these into a db table afterwards?
