If a request to an API endpoint is taking a long time to process, say 20 seconds, I found the kotlin client (3.7.3) will just crash the whole app.

Is it an expected behaviour?

```kotlin

Hi! 👋

It is expected that network exceptions (including timeouts) are thrown from the client, and as such they should be handled with a `try` `catch` block on the application’s side.

More information about error handling is available [here](https://www.apollographql.com/docs/kotlin/essentials/errors).

That being said, if you want to change the default timeout which is 1 minute, you can do so like this:

```kotlin
    apolloClient = ApolloClient.Builder()
        .httpEngine(DefaultHttpEngine(timeoutMillis = ...))
        .serverUrl(...)
        .build()

```

Thank you very much for your reply and confirmation. I will try the error handling approach as it is more resilient.
