Error while importing "__wbindgen_placeholder__"."__wbindgen_describe": unknown import. Expected Function(FunctionType { params: [I32], results: [] })

Describe the Bug

I am creating a SWC plugin for next js.
I recently started getting an error when running the plugin.

Now this error does not go away. Any recompiled plugin breaks the application. The same plugin compiled a few days ago works.

I reinstalled: cargo, rust, swc_core.

The error text brought me here. What does this error mean? Please help me understand.

In SWC they told me - check if all versions are latest. YES, but that's where their help ended.

Steps to Reproduce

I am completely following the instructions:
https://swc.rs/docs/plugin/ecmascript/getting-started
Run next js and I get an error.

The same plugin that I compiled a few days ago works in the latest version of Next js.
But everything I compile now breaks the application

Expected Behavior

The application must not break

Actual Behavior

Additional Context

I don't add anything other than the SWC starter kit. This is definitely not my fault.

I reinstalled everything except windows. I am ready to test any theory to solve the problem, and provide any information. Answer, please. I need any advice

SWC uses tracing for logging. By default, SWC testing library configures the log level to debug by default, and this can be controlled by using an environment variable named RUST_LOG.

Could you try setting RUST_LOG=trace and see if there's anything else in the logs?

i setting - RUST_BACKTRACE=1, RUST_LOG=trace, SWC_DEBUG=1

I'm not sure this is the place to ask this, probably better to figure it out in SWC, if it is a bug in wasm-bindgen a more minimal example, that doesn't involve tools outside wasm-bindgen, would be really helpful.

I asked this question to the SWC developers. Unfortunately they don't answer.

Why is this problem possible? I found a discussion thread with the same problem. In that case, another version of rust nightly helped. swc-project/swc#6883

I have tried this version and many others. And I will try all versions of rust. I have no other ideas :(

[daxpedda]

Looking at swc-project/swc#6883, the problem seems more clear now. The latest release seems to have broken WASI support, which is not actually officially supported by wasm-bindgen.

I encourage you to bring your use-case and point of view to #3421.
