this error showed up when i upgraded our webapp to kotlin 1.5.10

Module parse failed: 'import' and 'export' may appear only with 'sourceType: module' (9:0)
File was processed with these loaders:

i guess this is because webpack was updated, but i am completely clueless how to go about fixing this

[Ilya Goncharov [JB]]

You can use

kotlin.js.webpack.major.version=4

in gradle.properties to back to webpack 4

Possibly you use some custom loaders or plugins with not the latest version, and it can be updated to be compatible with webpack 5

it seems to fix itself by removing the handwritten bindings for

implementation(npm("@fluent/bundle", "0.16.1"))

[Nikky]

is there a current guide on how to write kotlin bindings for js code ?
the current ones i have seem to cause errors compiling

[Big Chungus]

Not really. It's mainly trial and error for each case, since there are so many ways to declare imports and exports in js...

found a fix for the library: https://github.com/webpack/webpack/issues/11597#issuecomment-705114717

now i am just left a different weird error related to karma

java.lang.IllegalStateException: command 'C:\Users\nikky\.gradle\nodejs\node-v14.15.4-win-x64\node.exe' exited with errors (exit code: 1)

i am not sure if that is webpack related or not anymore

[Nikky]

seems to be caused by using

usePhantomJS()
