Ok as far as I can see quickly you dont have the JS Coroutines lib added ```js compilations main defaultSourceSet dependencies implementation kotlin stdlib js implementation org jetbrains kotlinx kotlinx serialization runtime js $serializationVersion implementation io ktor ktor client js $ktorVersion implementation io ktor ktor client core js $ktorVersion implementation io ktor ktor client json js $ktorVersion implementation io ktor ktor client serialization js $ktorVersion ```

Jeff · Answer

It s there in jsTest

Jeff · Answer

```js compilations test defaultSourceSet dependencies implementation kotlin test js api io ktor ktor client mock js $ktorVersion api org jetbrains kotlinx kotlinx coroutines core js $coroutinesVersion ```

Sean Keane · Answer

But not in the main

Jeff · Answer

I am only using the code in the test Must it be there in the main too

Sean Keane · Answer

I suggest you give it ago slightly smiling face

Jeff · Answer

Just tried It didn t work

Dico · Answer

Js platform does not have `runBlocking` Native platform does if you have the dependency set up correctly

Jeff · Answer

So what should I do The expect function in common requires implementation in all target platforms

Dico · Answer

`block createCoroutine continuation ` or something like that I m not sure on js Js is single threaded so that s why runBlocking doesn t exist

Dico · Answer

You should be able to create a promise wrap it in a continuation and pass it to the coroutine then await the promise js style for example

Jeff · Answer

Do you have some sample code

Jeff · Answer

< Dico> promise isnt getting resolved Do I have to add a library

Dico · Answer

I don t know concrete details sorry

Jeff · Answer

Solved it
