In the new configuration, you need to provide the full file path (including the file name) instead of just the file name. You can use a variable for the file name, but ensure it’s part of the complete path.
Here are the three location options:
Local File System: Absolute path (e.g., C:\Users\Username\Reports\report_name.pdf).
Local Space: Relative to your KNIME workspace (e.g., knime://knime.space/Folder_name/report_name.pdf).
Embedded Data: Within the workflow’s data folder (e.g., knime://knime.workflow.data/report_name.pdf).
Create a variable for the file name and use it to build the full path (e.g., "knime://knime.workflow.data/" + $report_name$).
