Convert first sheet from an excel to a pdf file through power automate

Question

Hey, I have a flow that has worked for one and a half year and suddenly it stopped working. It stops on the convert file part from a Onedrive action. To save you from the kilometer of previous actions that do work it should be here where the fail lies.

"Conversion of this file to PDF is not supported. (invalidFileFormat / Error from Office Service. Url=https://euc.excelcs.officeapps.live.com/document/export/pdf HttpCode=UnsupportedMediaType)"

This is the error message and me, nor ChatGPT manage to find a solution to it. It is supposed to work to convert to pdf, but clearly it doesn't. Anyone who converts excels to pdf that has had this error pop up recently? Or know what to do?
