Node on tap not working?

[AlbaneseRemy]

Hello,

I'm adding nodes anchored to an image i'm tracking to my AR View.
But somehow, the on tap event is not triggering when clicking on the node. Please find my code at the end of the issue.

I don't have any error in my console but a line showing repetitively saying :

E/native (25852): E0000 00:00:1701099186.536445 25852 hit_test.cc:426] INTERNAL: No point hit.

Am I doing something wrong?

Thanks for your help

Also, I don't know if that is linked, but when I leave my AR Page, I get this error:
