Dynamic Deep Link URL in BI Publisher Report not working

Summary:

I have a RTF template that shows details of AR Invoices. I have inserted a link on Invoice Number to take the user to the transaction in the application using Deep Link. The deep link I have used is:

<serverurl>/fscmUI/faces/deeplink?objType=AR_TRANSACTION&action=VIEW&objKey=customerTrxId={TRX_ID}

When i try this locally using BI Publisher Desktop Add in, the link works perfectly. I am able to click the link and it takes me to the transaction in the application.

When I run the same report in Fusion, the TRX_ID value is not getting passed dynamically. If I copy the link generated, it shows me the below (without the trx_id at the end of the URL) .
