deployment error in NWDS for Iflow

Hello Friends,

I have developed scenario in PO 7.31 using NWDS iflow.

In development I have deployed the I flow correctly. Then transported to Quality system.

In Quality system, in NWDS iflow, made necessary changes and activated the Iflow.

When I try to deploy it, it gives me error as attached.

Deployment of integration flow 'XXXXXXXX failed.

An exception stack trace is not available.
