OAuth2.0 Custom Connector TestConnection Issue

[DavidEntekrity]

I have a working connector with PowerBI desktop and published this to service , I am unable to schedule a refresh in the service

When I edit the credentials I get the error below

I am using the code below for the TestConnection Handler
// Data Source Kind description
Xero_Isos = [
TestConnection = (dataSourcePath) => { "Xero_Isos.Contents" , dataSourcePath},
Authentication = [
OAuth = [
StartLogin = StartLogin,
FinishLogin = FinishLogin,
Logout = Logout,
Refresh = Refresh
]
]
,Label = Extension.LoadString ("DataSourceLabel")
];

Any help would be greatly appriciated

Hi @DavidEntekrity ,

Did you configure any gateway and using your custom connector with gateway? You can refer the content in the following links to get it.

1. Personal gateway

Configure Power BI Data Gateway

Use custom data connectors with the on-premises data gateway

2. Adding a TestConnection handler

How to enable scheduled refresh for your custom connector

Why does my Custom Connector not refresh?

Best Regards

Hi,

Yes, I have confirgured my Personnal Gateway and I do see the custom connector in the service
I also had added a TestConnection handler as below
TestConnection = (dataSourcePath) => { "Xero_Isos.Contents" , dataSourcePath}
Kind Regards
David
