This Account lacks sufficient permissions to use Merge Fields.' in Salesforce DocuSign Apps Launcher?
Is there way to resolve this without raising case.

I don’t think the Docusign eSignature trial account has Salesforce.com enabled as a feature.

You should be able to connect it to Salesforce.com environment without problems and do the desired testing with Docusign Apps Launcher.
