Hello, I have a question about file downloads within a app. We are using AP 5.2.3 and the latest Business Hub version. I am using a Python Script to create an Excel file which i would like to offer to the consumer as a download. The file is saved in a temp dir and the link will be provided via a download widget. So far, so good. It is working fine locally in Analytics Platfrom (output is a absolute path (C:.…) but not on Business Hub. Here the created temp file path looks like this: “/tmp/tmpc5m3tsuv\filenname.xlsx”. I have tried various options with tempfile in Python and with “Create Temp Folder” node. Both resulting in the similar problem. The created folder could not be handled and the file will not be saved Any idea how to solve this in a smart way? many thanks in advance! Lars

Hello @larsgrohmann , in general downloading file from the Business Hub should work. Somehow :slight_smile: The file path that you shared looks like a bit strange, suspicious, though: /tmp/tmpc5m3tsuv\filenname.xlsx It contains backslash (Windows) and forward slashes (Linux) in the same time. Are you sure your python script is correct? Would it be possible to share the script, the part of the workflow that you are using, for testing this? I’m not very familiar with python scripts but found that documentation: https://knime-python.readthedocs.io/en/stable/script-api.html#utility-functions Maybe the utility functions there can help you to get the correct file path? Cheers
