hey @minijohn, thank you for the fast reply :).
You can see my very simple UI screenshoted
In the container titled Documents, I have :
- pdfViewer component to display the PDF
- 2 buttons I created just to trigger the update. I did this to be more fast during the test phase. At the very end, only the sql request should update it.
In the query panel, you'll see my send_pdf_url query witch seems wrong since I have read your answer.
