'PVX data deserialization failed' during data transfer through SDATA after upgrade

Upgraded from v2014 to v2016.  When trying to transfer data from third party (Service Pro) to Sage 100 through SDATA, client is receive the following error:

{
"d": null,
"Message": "PVX data deserialization failed.",
"Errors": {
"Validation": [],
"General": [

{ "Error": "IntegrationException", "Details": "PVX data deserialization failed.", "ErrorCode": 49, "InnerException": "", "Data": null, "Source": "SPX.Services" }

]
},
"Warnings":

{ "General": [], "UnknownFields": [] }

,
"Affirmation": null
}

Double checked to make sure 'allow external access'  and 'Enable Native Provider and Access within Role Maintenance' are checked in setup.  Tried reinstalling Native SData Provider Adapter.
