Scheduling refresh with Web as datasource

Hi,

I have an issue regarding the schedule refresh for the online services.

My dataset is working fine where I use "Web" as datasource and fetching data from an API with a Bearer token provided in the header.

When refreshing the dataset on desktop everything works fine, no issues at all, I can get all the data I want.

The dataset can be published to online services without any problems aswell, all the data is preloaded with the dataset from when I refreshed the pbix file.

Then here is my issue where I try to set up a scheduled refresh, the warning triangel appears saying;

"Data source errorScheduled refresh is disabled because at least one data source is missing credentials. To start the refresh again, go to this dataset's settings page and enter credentials for all data sources. Then reactivate scheduled refresh."

And when I enter the settings of the dataset the Gateway connection says;
"You don't need a gateway for this dataset, because all of its data sources are in the cloud, but you can use a gateway for enhanced control over how you connect"

And under Data source credentials it says;

"Your data source can't be refreshed because the credentials are invalid. Please update your credentials and try again."

Though I dont use or have any Web credentials it is requiring this from me, all I Authorize with is a Bearer token which is passed by in the header.

Any suggestion why online services is behaving this way or any solution so that I can add a scheduled refresh to this datasource?

All help is appreciated.
