republish 'node' functionality is broken in Jazzy

[asimonov]

I summarised the problem with republish in Jazzy here: #275 (comment)

in that merge the 'node' was replaced by 'component', so any existing use of it as node now fails silently. not a great way to change API

I think you just need to change exec="republish" to exec="republish_node" in your launch file and your original will work.

There have been a number of updates in Jazzy. A fairly large, but not entirely comprehensive list is found in https://docs.ros.org/en/rolling/p/image_pipeline/changelog.html - it looks like this wasn't included, a PR to add that would certainly be merged. EDIT: I missed that this is image_common, not image_pipeline - I don't know that any of the docs for image_common have actually been migrated to docs.ros.org
