Hi Team,

I am facing the same issue where MergedPDF action is throwing the input file error for application/pdf MIME type. I am passing the pdf file name from PowerApps to Power Automate then getting the file content from SharePoint connector and appending to array variable

    Hi @v-xiaochen-msft 

    If I remove the array after clickin that icon its giving error while saving -"Flow save failed with code 'OpenApiOperationParameterValidationFailed' and message 'Input parameter 'Files Array' validation failed in workflow operation 'Merge_PDFs': The parameter with value '"@{variables('MergedContentArray')}\n "' in path 'Files Array/files' with type/format 'String' is not convertible to type/format 'Array'.'"
