A SharePoint list that contains data required for this form to function correctly cannot be found

We are replicating one of our SharePoint online site to another SharePoint online site. The source site has an InfoPath form which used to deploy to a form library. When we save the form library as a template in the source site where the InfoPath form has been developed and deploy in the destination site that time InfoPath form comes. But when we open the InfoPath form in the browser to fill and submit it gives the below error:

Hey there!
Check the information in this link

Your destination SharePoint site is missing reference list required to run Infopath form. If you have infopath form in machine, design and check existing data connections used. This must be one of the lists referred in Data Connections.
