Please try approach from #1915

this approach didn't work for me, all parameters still take default values

[vooon]

Strange. Soryr, what ros2 release you're on?

[hasanosman601]

@vooon Foxy release because I'm using ubunut20, but I looked at the documentation for both the Foxy and Humble release about parameters as they have the same documentation so I don't know if the issue is related to the Ros2 distribution I'm using

[vooon]

@hasanosman601 that's unclear, but some features changes quite hard comparing to older releases.

[hasanosman601]

@vooon ok, I'll keep this change since it works for me on Foxy release.
