REST Order Details Null Excpetion

When adding line Order Details I get this .
Was working. Anybody else run into this?

{“CustNum”:961,“PartNumPartDescription”:"",“Company”:“ROCELEC”,“UnitPrice”:“10.0”,“RequestDate”:“2020-11-20”,“OrderNum”:1053441,“OrderQty”:“10000”,“NeedByDate”:“2020-11-20”,“PartNum”:“testpartsupplier”,“LineDesc”:“Place Holder”}

“HttpStatus”:500,“ReasonPhrase”:“REST Api Exception”,“ErrorMessage”:“BPM runtime caught an unexpected exception of ‘NullReferenceException’ type.\r\nSee more info in the Inner Exception section of Exception Details.\r\n”,“ErrorType”:“Epicor.RESTApi.ErrorHandling.ApiException”}

Fixed it. The data being fed to me contained bad part number. Should have noticed that myself.
Ugggg

As a note, this mentions a BPM error. If you are getting this error with a bad part, you likely need to give a better error than “Null Reference” in your BPM.
