Decorators support with @node-swc/register sparks problems. Nothing works :'(
When trying to transcompile my typescript files I get this error :'(

Any idea on how to fix the issue? Thank you in advance i have been stuck with this issue since 3 days now :(
Side note: The error appeared once I upgraded my node version to 19.x
Is this issue related to the one I have? https://github.com/swc-project/swc-node/issues/701
I am still trying to figure out how to fix this issue. Please if anyone can help I would be more than grateful!
@ElMehdiBouamama you should provide a minimal reproducible repo for your issue so that I can debug it
Got the same issue. @Brooooooklyn could you help.
