[bhavinmac]

General Info

• I installed the latest version of Supabase-Kt
• I checked for similar bug report

What happened? (include your code)

class SplashKotlinActivity : AppCompatActivity() {

val supabaseClient = createSupabaseClient {
    supabaseUrl = "https://MY_KEY.supabase.co/realtime/v1"
    supabaseKey = "SUPABASE_KEY"

    install(Realtime)
}

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_splash)
    initializeAndroid(supabaseClient)

}

add this dependency

implementation("io.ktor:ktor-client-cio:2.1.1")

[jan-tennert]

Yes you need a Ktor Client Engine, might include this in the readme

[bhavinmac]

add this dependency

implementation("io.ktor:ktor-client-cio:2.1.1")

Now getting error "java.lang.IllegalStateException: The schema must be specified"

[jan-tennert]

Also the supabase url should just be https://MY_KEY.supabase.co
If you want to have a different URL just for realtime, you can change it in the realtime config but supabase-kt handles the urls for the different modules automatically

Now getting error "java.lang.IllegalStateException: The schema must be specified"

This exception is thrown if you try to listen for db changes without actually specifying a schema.
See https://github.com/supabase-community/supabase-kt/tree/master/Realtime under Listening for Postgres changes for more informations

This actually bugs me. Even though I like the DSL style for settings, it doesn't force the consumer to provide required arguments and results in crash at runtime and it increases difficulty for new users. So maybe we should force required args as function arguments.
e. g.

createSupabaseClient(
    supabaseUrl = "https://MY_KEY.supabase.co/realtime/v1"
    supabaseKey = "SUPABASE_KEY"
) {
    install(Realtime)
    ...
}

Even more so now when this library is part of supabase community (congrats btw :) great job). So there is actually a danger of people using it :D

Thanks, yea you are right, maybe I should change that!

I'd close this issue to keep things clean. Feel free to open another issue when you have any issues!
