Automatic refresh fails

Hello to the forum,

I have created 2 dataflows in the Power BI service in a workspace with a Pro license. I imported these into Power BI Desktop. In Power BI Desktop, I then combined both dataflows in Power Query using an append query. The dataset is named “Append1”. (I know I could also do the append query in the Power BI service, but I don't have the premium license for that).

Append of the two dataflows in Power Query

In Power BI Desktop I only loaded the “Append1” dataset into the data model. I only saved the two dataflows in the connection.

I then published my report to the Power BI service. For this I used the workspace in which the two dataflows are still located.

Upload of the dataset "Append 1"

I then created the automatic refresh for the two dataflows and also for the dataset in the workspace settings. However, the automatic refresh for the dataset fails. With both dataflows, however, it works without any problems.

Here are the settings of the dataset in the Power BI service:

Settings of the dataset

The error message is:

Can someone help me?
