Data Source Credentials with Custom Connector Problem

[ariam]

Hello!

I have a custom connector that can't get past the data source credentials on PowerBI Web version in order for me to schedule a data refresh, even though it works fine on the Desktop version. I narrowed the problem down to the "TestConnection" part of the connector code, but I cannot figure out what to do from here to fix the error. This connector was written in 2018 so I'm hoping someone knows what I can do to update the code to work.

Here is the line of code:

Error message:

Error message when I try and sign in after selecting Edit credentials:

According to Microsoft's website, the problem lies in my test connection but I cannot seem to find how to fix that. Ideally I would love to write the code to skip the test connection but I don't know what to use for that. Additionally, when I try and fix it from the data gateway, it says I cannot skip the connection and it doesn't show any option to select when I try and select an authentication method:

I appreciate anyone's help with this!

Hi @ariam ,

Have you tried to republish the .pbix which works fine in Desktop to Power BI Service and then configure the gateway again?

I have yes but it doesn't seem to work still. I think the problem is specifically with the testconnection line of code and I read somewhere that the test connections may not like API's being used, but I am hoping there is a way to bypass it or to re-write the code to only look at the website and not the API.
