# coroutines

Hi folks, I have a question as a relatively newbie in the coroutine world. I'm trying to refactor this piece of code:

val oas = specs.map {
    async {
      try {
        client.get(it).body<OpenApiSpec>() // Ktor HTTP client
      } catch (e: ClientRequestException) {
        null
      }
    }
  }.awaitAll()

I'd like to abstract away the exception handling, so I've tried something like this:

suspend inline fun <reified T> HttpResponse.bodyOrNull(): T? = try {
  body()
} catch (e: ClientRequestException) {
  null
}

val oas = specs.map {
  async {
    client.get(it).bodyOrNull<OpenApiSpec>()
  }
}.awaitAll()

But instead of swallowing the exceptions and returning null as in the example above, I get the exception bubbling up. I suspect I'm not yet fully understanding the exception handling model for coroutines, could anybody help shed some light? Thanks in advance.
(Btw, I obtain the same result if I wrap the try/catch with coroutineScope)

Solved the problem by myself. In case anyone will wonder or is curious, it's get() throwing an exception, not body() so it makes sense that my refactoring has no effect
