I have a flow triggered by a button in PowerApps to generate a PDF. It has suddenly stopped working for no apparent reason. I built the flow using this video as a guide Create a PDF from SharePoint Data using Power Apps and Power Automate flow for free (youtube.com) and has worked flawlessly for the last year+. I can see in OneDrive for Business that my HTML text file is generating, but the PDF has no content, so I am not sure at what point of the process it is breaking.

My outputs look empty and are shown here:


Has anyone else experienced this and is there a solution?
Thanks!
