Perform Microsoft Word Mail Merge on Salesforce using Aspose.Words REST API issue

We are using Aspose to generate PDF and Word documents. We are using Aspose in cloud from SFDC. This was working fine all this while but we started getting an issue since today morning. The error that we get from API call is below. We had similar issue in past which fixed itself. But today this error is still persisting in our production environment.







System.HttpResponse[Status=Bad Request, StatusCode=400]

Response Body {“Message”:“Object reference not set to an instance of an object.”}
