PayloadSwapBean not working in Production PI 7.3 AEX

Hi,

I am facing a very strange problem.

The scenario is Read Email attachment and place the attachment in NFS folder.

The interface is working fine in DEV and Quality . But unfortunately not working in Production

1     swap.keyName     Content-Disposition

1     swap.keyName     Content-Description

1     swap.keyValue     attachment;filename="XYZ- ABC.csv"

1     swap.keyValue     XYZ

Same Email is sent to all the 3 environment - but it is working in DEV and QA .

In production i am getting message "Swap: no matching payload found"...

If anyone has faced this issue- appreciate if you can share the root cause.

Thanks

Biplab
