Error when loading extism plugin which uses lingua

[Nutomic]

I am currently trying to develop an extism plugin which uses lingua. The plugin itself compiles fine using the Extism Rust PDK instructions. But when loading the plugin it throws the following error:

Unknown: crates/api/api_utils/src/plugins.rs:135:36unknown import: `__wbindgen_placeholder__::__wbindgen_object_clone_ref` has not been defined

Here you can see the source code. If I remove the lingua dependency then the plugin works without any errors. From what I understand, lingua should be able to run in Webassembly. Do you know how to fix this problem?

Do you know how to fix this problem?

Unfortunately, I don't. I'm not familiar enough with Extism yet but my goal is to change that so that I can work on #512 which you have probably seen already. My guess is that wasm-bindgen is not compatible with Extism and ought to be disabled before compilation.

You were right. It seems that wasm-bindgen is used for interop between JS and Rust, but as Extism doesnt use JS it doesnt support wasm-bindgen (and doesnt need it anyway).
