Expected Behavior

Could be that the deprecation warning comes from Puppeteer, if that is the case there isn't much to do (BSI already uses latest available Puppeteer version).

Either way, it would be good to fix the issue if possible, or at least suppress the warning.

To Reproduce

No response

[mountaindude]

Only happens when installing browser, not when browser is already installed.
Confirmed to happen on both macOS and Windows 11.

Setting an env var before starting BSI works (macOS here):

NODE_OPTIONS="--no-deprecation" ./butler-sheet-icons qseow create-sheet-thumbnails ...

Adding that option to env when BSI starts may do the trick.
