Unable to Refresh from Gateway server

[jlriverayuso]

although the data refreshes fine form othe Personal Mode Data Gateway, when published to the Power BI Service i just get the following error: 

{"error":{"code":"DM_GWPipeline_Gateway_InvalidMashupConnectionString","pbi.error":{"code":"DM_GWPipeline_Gateway_InvalidMashupConnectionString","parameters":{},"details":[],"exceptionCulprit":1}}} Table: -- Cluster URI: | usgovcloudapi.net

Hey @jlriverayuso,

have you made sure to enable "Allow user’s custom data connectors to refresh through this gateway cluster" when setting up the gateway in the Power BI Service and did the connection test work when configuring the data source?

Hi! @pichlerpa , yes, this option has been enabled. that error comes up when it tries to refresh the data.

Hi @jlriverayuso,

That's difficult to troubleshoot, but you could download some sort of HTTP sniffer such as Fiddler for checking what HTTP requests are being sent and what's going on behind the scenes. It worked on my end before uploading the .MEZ file using a non-personal gateway.

Hey @jlriverayuso,

It seems to like the Power BI service finally can't access the custom connector, maybe somehow related to the first point here: https://learn.microsoft.com/en-us/power-bi/connect-data/service-gateway-custom-connectors#considerations-and-limitations

@pichlerpa seems that you were right. we had to change the location of the Custom Connectors folder and allow authenticated users to execute anything in the folder. thank you so much!
