Troubleshooting
Most messages mean the .ipynb is missing from this page, the file is over 2 MB, or the chart was saved as HTML instead of PNG. The page does not run the notebook.
Updated .
Choose a notebook
The macro was inserted without a file. Edit the page, open the macro, and select the .ipynb attached to this page.
Missing file
The saved filename is not in the current attachment list. Attach the file to this page, or edit the macro and choose a file that is attached.
File size
The file is over 2 MB. The app stops before reading it. In Jupyter, clear oversized outputs, save, and attach the smaller file.
File format
The file is not valid JSON, or it is not nbformat 4. Save it again from Jupyter and attach the new file.
Download
The attachment could not be read with your permission to the page. Confirm you can download the file from the page attachments, then reload.
Subscription
The app is paid. An administrator checks Jupyter Notebook Viewer for Confluence under Apps, then Manage apps. A production install uses the Marketplace subscription.
Empty list
Attach the .ipynb to this page, then close the macro dialog and open it again. You can also type the filename. The name has to match the attachment.
Missing chart
The chart was probably saved as HTML, SVG, or a widget. Re-run the cell so Jupyter also stores a PNG or JPEG, save the notebook, and attach that file. See what is left out.
Different view
That is expected. The app shows a reading view of the saved file. It does not start a kernel, and it does not display HTML.
Support
Email tim@upgradesolutions.io with the page URL, the attachment filename, and a screenshot of the message.
