Do you need log-file?
Other steps (hacks). Edit export.js:
browser = await puppeteer.launch({
+ platform: 'linux',
+ executablePath: '/usr/local/bin/chrome',
headless: true,
In tomcat/webapps/draw/js/PreConfig.js (https://github.com/jgraph/drawio/blob/dev/src/main/webapp/js/PreConfig.js):
-window.EXPORT_URL = 'REPLACE_WITH_YOUR_IMAGE_SERVER';
+window.EXPORT_URL = 'http://IP:8000/node/export';
Tried export in PDF - files always have 11 bytes: "BAD REQUEST".

It (export server) doesn't work via http if server with nextcloud and/or drawio are on https! Probably it's a browser fault.
Is it possible to bind on specific IP:PORT without hardcode export.js? Is this the description:
Then add export=http://localhost:8000/ (hostname and port as needed) as an URL parameter to use that service for development and testing.
How to use it?
