Custom connector not showing when configuring gateway in PowerBI Service

[Anonymous]

Hi community,

I have developed a custom connector which I tested in PowerBI Desktop. I also managed to publish to the PowerBI Service and schedule a refresh using a personal gateway. So far everyting works fine. Trouble starts when I try to configure a refresh using a standard gateway as described here: https://docs.microsoft.com/en-us/power-bi/connect-data/service-gateway-custom-connectors. 

I have a On-premises data gateway (version 3000.106.11) running on my computer, placed my connector file (.mez) in the right folder, and it's showing up in the gateway:

I can also connect to my gateway in PowerBI Service, but when I want to add a new data source to it, my custom connector is not showing in the dropdown:

Some help will be much appreciated.

The issue has been resolved. The problem was with the implementation of the TestConnection method in the connector code. The main method of the connector had 2 parameters of type Date. I changed them to type text and changed the TestConnection method from:

TestConnection = (dataSourcePath) => 
	let
		params = Json.Document(dataSourcePath),
		startDate = Date.FromText(params[startDate]),
		endDate = Date.FromText(params[endDate])
	in
		{"MyConnector.Data", startDate, endDate}

to:

TestConnection = (dataSourcePath) => 
	let
		params = Json.Document(dataSourcePath),
		startDate = params[startDate],
		endDate = params[endDate]
	in
		{"MyConnector.Data", startDate, endDate}

and now I can select my connector in PowerBI service.

Hi @Anonymous ,

Please refer to the following topic to see if it helps you.

1) First of all uninstalled "Personal mode" gateway and installed "Standard mode" gateway

2) Went to services -> On-premise data gateway service->Properties ->Log on-> Select Local System Account and check box "Allow Service to interact with desktop"

3) Went to Gateway -> Connectors tab -> Pasted the location where custom connector file is residing

4) Restarted the gateway

Hi @Anonymous ,

Please ensure the connector is certified.A certified connector is:

• Built by the developer
• Evaluated by Microsoft
• Distributed by Microsoft
• Maintained by the developer
• Supported by the developer

This program will allow owners of data sources to deliver connectors seamlessly via Get Data in Power BI, making it easy for you to take advantage of the capabilities of Power BI and the breadth of our audience.

Do I need to have my connector officially certified to work with the enterprise gateway? I thought by using a gateway I didn't have to go through the certification process and just use the connector internally in our organization.

If I understand the document you posted correctly, custom connectors should be fully supported in the enterprise gateway and PowerBI service without certification.

As for the other topic, the problem doesn't seem te be with the gateway itself. I have the latest version installed and I can see my custom connector in the gateway. It's just not showing up in PowerBI Service.

Hi @Anonymous 

Please make sure you have the below setting checked in on gateway settings of your cluster

This should allow to use custom data sources.

I already had the "Allow user's custom data connectors..." setting checked, and I also tried with the other 2 settings checked, but unfortunately it's still not showing in the dropdown.

Did you restart On-Premises gateway service after adding custom connector?

Check out below link also:

Yes I did restart it.

At first I thought maybe it had something to do with with access rights on my computer. So I tried putting the connector file in different folders and using different service accounts for the gateway. But still no luck.

I also tried the solution to this post: https://community.powerbi.com/t5/Service/Configuring-custom-connector-in-Power-BI-service/m-p/164424.... But that doesn't work either for me.
