There is an Exception throwed when trying to get keys using custom JWT with below function, and network is on SAPPHIRE\_DEVNET.

```auto
@RequiresApi(Build.VERSION_CODES.O)
    fun signIn(){
        try {
            val sub = "2cgkq"
            val idToken = "CUSTOM_JWT_TOKEN"
            loginParams = LoginParams("test-app", sub, idToken)
            torusKey = singleFactorAuth.getKey(
                loginParams,
                context,
                86400
            ).get()
            publicAddress = torusKey?.publicAddress.toString()
            Log.d("Web3Auth", """Private Key: ${torusKey?.privateKey?.toString(16)}""".trimIndent())
        } catch (e: ExecutionException) {
            Log.d("Web3Auth", e.message.toString())
        } catch (e: InterruptedException) {
            Log.d("Web3Auth", e.message.toString())
        }
    }

```

Exception:

```auto
java.util.concurrent.ExecutionException: java.lang.IllegalArgumentException: Expected URL scheme 'http' or 'https' but no colon was found

```

Hey @nethaji can you share the Android SFA version you are using, also is this exception triggered when you are doing getKey?

I’m using the following versions in my project:

```auto
implementation 'com.github.Web3auth:single-factor-auth-android:0.4.0'
implementation 'org.torusresearch:fetch-node-details-java:5.0.0'

```

And yes, I’m encountering an exception when I call `getKey`."

The error you are getting is more of HTTP url not being correct, not sure if it’s from Web3Auth. I’ll try our example. Can you get the stack trace for the error?

Hey, I tried to reproduce the error. It’s working fine, can you please share the detail stack trace for the error?
