Any idea why I am getting this error

[amar_1995]

I tried to run suspend function in both IO and Main thread. But yet facing this issue

[amar_1995]

I am getting this error by running this code.

withContext(<http://Dispatchers.IO|Dispatchers.IO>) {
            internationalArticle = articleService.getTopHeadLine(token, options)
        }

[amar_1995]

But now when I change my code to below piece of code, resolves the issue.

runBlocking {
   launch(<http://Dispatchers.IO|Dispatchers.IO>) {
        internationalArticle = articleService.getTopHeadLine(token, options)
        println("Server data: " + internationalArticle)
    }
}

Don’t think coroutines is fully supported by the new IR compiler yet.
