Deployment Pipeline - Workspace includes unsupported items

Dear Community, 

Requesting your help here.

While creating a deployment pipeline, i am facing the below error...Still it is allowing me to continue (which is of no use)

This above error comes up when i create a deployment pipeline and assign a premium workspace account "Global_Operations" to Development stage.

This premium workspace has hosted reports and dataset built using import query on SQL DBs  (AWS hosted). Plus the reports and dataset complies to the pre-defined conditions of Deployment pipeline  - 

• Datasets that do not originate from a .pbix -

• Reports based on unsupported datasets

• The workspace cannot use a template app

• Paginated reports

• Dataflows

• PUSH datasets

• Workbooks

so the problem is - I am unable to find out what exactly is the issue with my dataset or report that needs to fixed so that i can use the deployment pipeline.

Kindly suggest...
