Hi,
I am trying to refresh a data gateway to run on  a Windows server VM which is hosted on Azure
The challenge is whenever I am refreshing my dataset on Power BI service, an error message is displayed saying "The key didn't match any rows in the table" 
A sample of which is shown below:
Underlying error code:  | 
-2147467259 Table: org_site.  | 
Underlying error message:  | 
The key didn't match any rows in the table.  | 
DM_ErrorDetailNameCode_UnderlyingHResult:  |

[Schema = "d1272", Item = "org_site"]  | 
Microsoft.Data.Mashup.ValueError.Reason:  | 
Expression.Error  | 
Cluster URI:  |
