any idea?

I get the same also with a hello world wallet that I made by following the quick start guide in https://docs.lightspark.com/lightspark-sdk/quickstart?language=Go

Ok, after debugging a little bit, the problem is with the go version 1.24, with the 1.23.7 all works as expected

Thanks for filing this @vincenzopalazzo! We actually had a customer reach out about the same issue. The root of the problem is this issue with uniffi-bindgen-go, so we may need to replace our internal rust lib with a native Go implementation. If you're able to work with Go 1.23.7 for now, that's great. We're working on unblocking the upgrade, though.

cc @shreyav who's working on this.

Hi @jklein24 thanks for the clarification :)

Go 1.23.7 works as expected tho probably a compiler check change. Anyhow thanks to look at this

[shreyav]

@vincenzopalazzo This is fixed in the latest version of the sdk (v0.16.0), please let us know if it works for you!

@shreyav, trying to test it by the end of the week
