bug? can't submit my script due to syntax error.

§
Posted: 2023.06.21.

Hi :)

I'm trying to publish a script but sadly Greasy Fork detects a syntax error :
Uncaught SyntaxError: await is only valid in async functions and the top level bodies of modules

However, i know the "await" lines and the whole script work perfectly fine on chrome.
Do you know if there is a good workaround for this kind of problem?

the script can be found here on github : https://github.com/FlambyGeo/MAGGAscript

the "faulty lines" are the lines that load image ressources defined in @resource such as :
var background_URL = await GM.getResourceUrl(imageBackground);

thank you ^^

I guess chrome might have already wrap it in async function.

In "true" javascript, you have to wrap it in async function by yourself.

And always wrap your script inside a function. Otherwise your script will create variables in global scope directly.

Here is a simple reference for you to learn the concept of async/await.

Actually your async function removeBackgroundFirstPass() does not require async. It is just a normal function.

There is no await inside
