Scheduled Refresh Failure - Value cannot be null

Hi -

 

I'm running into an issue with my scheduled refresh. I'm using a custom connector and personal gateway. Everything works so long as I keep my data limited to one table. Unfortunately, anytime I have a report with more than 1 table (same Data Source - the Custom Connector), I receive the below error:

 

There was an error in the data gateway.Hide details

Underlying error message:Value cannot be null. Parameter name: accessToken Table: funds.

 

The manual refresh works fine within Power BI Desktop. I've tried unchecking "Autodetect new relationships" but nothing helps.

 

Thanks!

    Which data source are you connecting to? Please check if the access token has been expired. Make sure you have installed the latest version of data gateway.
