MarkLogic DHF 5.2.1 QuickStart - Local Setup - Flow not found

Question

I tried to setup DHF 5.2.1 after upgrading from ML9 to ML10 in my local. QuickStart Setup was smooth and I created an entity and flow as well. When I ran the flow, I got the below error:

Local message: Could not apply resource at documents. Server Message: The specified flow GradeIngestionFlow is missing.

GradeIngestionFlow is my flow name. I tried to use the option "REDEPLOY" on flows tab and ran after that and still got the same error. I could also see the flow under 'C:\DHF\flows'. Below is the full error log from JOBS DB. Can someone help in debugging this error?

}
}
}
}

I'm yet to try setting up using gradle.
