[bug] _tauri_plugin_functions not defined

[AyuBloom]

I'm not sure if i missed any steps in README.md, but i would get the following error when the app runs:

thread '<unnamed>' panicked at /Users/rdm/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/tauri-plugin-deno-0.2.0/src/deno_lib.rs:98:10:

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

And when i call the function in the frontend, it gives me this error:

called `Result::unwrap()` on an `Err` value: SendError { .. }

My src-deno/main.js:

function greetJs(input) {
  return input + " from main.js";
}

_tauri_plugin_functions = [greetJs.name]; // This will make the function "greetJs" callable from UI

Appreciate the help!

I forgot to mention, I ran the app in Rosetta 2 since i have trouble building libffi during npm run tauri dev.

Hi!
Sorry - I currently don't have much time to check for this.
I guess this could be related to Rosetta 2. I usually build this on my M1 natively and I don't have issues. The error mostly means that deno couldn't find _tauri_plugin_functions and therefore the code panics. Maybe this is some encoding issue, so that deno can't parse the js file correctly.

Anyway - I also have no idea how to replicate this.

Can you run tauri without the plugin without issues?

[AyuBloom]

Hello! I can confirm that I can run Tauri normally without the plugin. The error might be what you have speculated - running the project with some parts on Rosetta 2.

After installing the plugin via npm run tauri add deno and also installing deno itself via npm i deno (I'm not sure why I did this, but alas that was my setup) but I just couldn't build natively as it would throw an error like this:

I used Rosetta 2 by running the tauri dev command again but in the Rosetta 2 shell.

This is the most information I think I could give you now.
