Create Pdf with power automate is possible but does not appear in SP - Why?

[PowerSäm]

Hello everyone, I have the following problem...

I am currently building a function that allows to create pdfs in powerapps using HTML and Power Automate. So far I have built everything and it works. The flow goes through without showing any errors. Unfortunately there is no generated pfs in sharepoint, although it should be there. When I try to start the flow again, it runs almost to the end, but tells me that a pdf with the same name is already stored in sharepoint.
How can this be? When I go to the list in sharepoint, the list is empty. Is it possible that the entry is somehow hidden or not displayed?

Very strange. I am getting desperate... (For more details see pictures)

Thanks in advance!
