typealias NetworkError = kotlinx.io.IOException

with a multiplatform project
apparently typealiasing an expected exception doesn’t really work
If I do the above and than try to

try {
  // ...
} catch(e: NetworkError) {
}

I get this error:

Throwable type mismatch: actual type is 'kotlinx.io.IOException'.

It isn’t a big deal, I can use kotlinx.io.IOException directly, I just wanted to ask if this is an intentional limitation or if there’s something going on here, cheers

I should probably mention that this error isn’t always showing up..

This is what I have, 3 modules:
• shared:network
• shared:api
• shared:usage
so in the network module I defined the typealias

the api module declare an API like this:

interface MyApi {

  @Throws(NetworkError::class, CancellationException::class)
  suspend foo()
}

finally the usage module call the MyApi and try to catch NetworkError.

Both the api and the usage module have the network module as dependency

The only reason I wanted the typealias is that I wanted my network library to be part of the API instead of the kotlinx-io library
