We have installed ABBYY FlexiCapture software on an on prem windows server. And we installed Pega connector on the Pega Cloud according to instructions in "ABBYY® FlexiCapture® 12 Connector for Pega Administrator's Guide". Can be downloaded at https://downloads.abbyy.com/FC/CONNECTORS/Pega/FC12ConnectorsPega Proprietary information hidden/FC12PegaConnectorGuide0.pdf?secure=Elboszoge9_2lWH5moAO4w== We are now trying to test the functionality from Pega but we see below error: Exception while invoking function: nsbcbsmnmr_abbyy.SendForProcessing--(String,String), Failed to open session for the role type

Log from Abbyy Flexicapture app server IIS:

2022-06-16 19:35:33 Proprietary information hidden POST /flexicapture12/Server/API/v1/JSON/FlexiCapture12/Server/FCAuth/API/v1/Soap - 443 [email protected] Proprietary information hidden HTTP/1.1 Axis/1.4 - 500 0 0 2 Basic+c3ZjX2ZsZXhpY2FwX2FkX1FAYWQuYmNic21uLmNvbToybFc5cThqRE9NQ0E=

But when we test the endpoint from Postman, we get correct response and a new session id is returned as expected.

What we noticed is when we hit the endpoint from postman we are hitting /flexicapture12/Server/API/v1/JSON where as from Pega we are hitting /flexicapture12/Server/API/v1/JSON/FlexiCapture12/Server/FCAuth/API/v1/Soap

Is /flexicapture12/Server/API/v1/JSON/FlexiCapture12/Server/FCAuth/API/v1/Soap correct?
