Kobweb API call to Firestore with error: "Address types of NameResolver 'unix' not supported by transport"

[pawchi]

Hi,

In my kobweb project I have two modules:

• jsMain where I have frontend in kobweb.compose,
• jvmMain where I have backend with API access point.
  If I test method getCompanySettings() (i.e. starting from main()), everything works fine and I receive data from Firestore. If I test @Api getSettings in localhost with some String as response - also everything OK. I get the String in my WWW, but if try to get response from Firestore in my WWW, than I receive an error:

Error: java.lang.IllegalArgumentException: Address types of NameResolver 'unix' for 'firestore.googleapis.com:443' not supported by transport

import com.varabyte.kobweb.api.Api

@Api(routeOverride = "getSettings")
fun getSettings(context: ApiContext) {
    val result = getCompanySettings()
    context.res.setBodyText(result)
}

fun getCompanySettings():String{
AppUtils.initializeFirebase()
    try {
        val future = com.google.firebase.cloud.FirestoreClient
            .getFirestore()
            .options.service
            .collection(AppConstants.FB_COMPANIES_COLLECTION)
            .document("test1")
            .get()

        val snapshot: DocumentSnapshot = future.get()
        if (snapshot.exists()) {
            return snapshot.getString("settings").toString()
        } else {
            return "Snapshot not exists"
        }
    } catch (e: Exception) {
        return "Error: ${e.message}"
    }
}

I have tried everything. Am I doing something wrong?
Any help appreciated!

I have put also the question on stackoverflow but no answers:

I'm not too sure. I've never heard of this before. It's possible the way I'm buliding the server jar isn't merging a file you have in your project correctly.

What service are you using to host your fullstack site? Can you share your build.gradle.kts file? Do you have any files under your resources/META-INF/ folder or some other weird setup like that?

Also, can you try this, locally (in case you haven't already)?

$ kobweb export
$ kobweb run --env prod
