I'm using REST Data API in FileMaker 16 and trying to insert a new row into a table which has a related table. There is an Order and the Order has Line Items which is stored in another table/database. (I'm new to FileMaker and working with a third party project.)
This is my attempt to do this though I'm not sure if this is the right way:
The call succeeds if I don't include the LineItems(0) section which is stored in a related table. This is the error I'm getting:
"errorMessage": "Value in field failed calculation test of validation entry option",
Am I taking the right general approach to be able to create the order and line item in a single POST call? Any suggestion for how to debug?
