**Error while refreshing semantic model on Power BI service connected to Databricks backend**

Hello,

I have deployed a model on the Power BI service. When I try to refresh it, I get the following error after about an hour or so of refreshing 

Data source error: {"error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","pbi.error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","parameters":{},"details":[{"code":"DM_ErrorDetailNameCode_UnderlyingErrorCode","detail":{"type":1,"value":"-2147467259"}},{"code":"DM_ErrorDetailNameCode_UnderlyingErrorMessage","detail":{"type":1,"value":"ERROR [HY000] [Microsoft][Hardy] (35) Error from server: error code: '0' error message: 'Unable to continue fetch after reconnect. Retry limit exceeded.'."}},{"code":"DM_ErrorDetailNameCode_UnderlyingHResult","detail":{"type":1,"value":"-2147467259"}},{"code":"Microsoft.Data.Mashup.ValueError.Reason","detail":{"type":1,"value":"DataSource.Error"}}],"exceptionCulprit":1}}} Table: [Table_Name].

The model refreshes on the pwoer bi desktop. It also refreshes on the PBI Service, if I limit the number of rows returned to something less 20million- through a parameter. The data source is Databricks sql warehouse. If I am missing any pertinent piece of information please let me know. 

 

Thanks in advance for any help.
