Error when trying to update automatically

[gdps_vc]

I created a report using 4 Excel's files.

The files are daily sent to my email, where through a power automate flow are saved inside a sharepoint.

The 4 files contain different information, however they are all inside the same folder and I'm importing using the web connection.

Using Power BI Desktop, I was able to update the report without any problems. But when trying the scheduled update, I'm getting the following error:

Any idea how to solve this problem? I wouldn't want to have to manually update and republish the report every single day.
