Why does the Report PDF Write Node create such strange file names?

KNIME Analytics Platform

Hi there,

went through the L1 training with some learners this week and we noticed a very strange behavior.

E. g. in the very last exercise you should create a pdf using the Report PDF Writer with data that comes out of the component (this workflow here: Customer Transactions Analysis - Solution – KNIME Community Hub )

However, the file name looks really strange. E. g. in my workflow, the file was clearly exported as test.pdf and is also stored as test.pdf, my pdf application shows a very strange “document title”.

Is there any way to avoid this (might be confusing especially to new people) or control this?

Hello @kowisoft,

you can use Bundled Chromium as browser for PDF generation (advanced settings in Report PDF Writer; need to install extension before you can use it) and you will get proper name in PDF tab.

Claude AI: “So Chromium is simply doing a better job of setting the PDF metadata title — probably using the file name as a fallback when no explicit <title> is present in the HTML, while CEF just passes through the raw temp path.
…
The CEF behavior looks like a bug or an oversight in the extension.”
