Error Ingesting Data from Salesforce

Hi all, 

I am trying to ingest data from Salesforce, using the OOTB Salesforce Source Connector. I already have the connection setup, but after mapping all the fields when I click on 'Finish' to save the dataflow; I get the error "An error has occurred while validating patch instructions: Invalid JSON Patch payload (missing 'value' field)" 

I am not sure what's causing this error and how to resolve this. Any help is appreciated. 

Thanks!
