Hi @gsasikumar I’ve resolved the issue by adding Registration preview template to Master. Now I have annother issue with the final step, after giving the username and password it shows an alert with the message **“Unable to load Registration Acknowledgement Screen”** after debuging I found that the **Registration Acknowledgement Template** is missing in **reg.template**. I’ve searched at master.template for the template and I found it, but while MasterData Sync there is a query that is searching for templates with module id = 10002 but **Registration Acknowledgement Template** have 10005. So I decided to duplicate the template with the module id 10002. Now the template is found ![image](https://europe1.discourse-cdn.com/flex017/uploads/mosip1/original/1X/3150e57a082714a44e72567b2a6eb236cfef8c00.png) but I have this error :

Can you share the template please ? Looks like a parsing error in velocity template ---
