js-api fails to connect in example app

[ashishbeck]

When I press the connect button in the example app, it keeps staying in the loading state forever and the following comes up in the logs:

I/flutter ( 2705): CONSOLE MESSAGE: 2021-08-01 10:32:05        REGISTRY: Unknown signed extensions SetEvmOrigin found, treating them as no-effect
I/flutter ( 2705): CONSOLE MESSAGE: 2021-08-01 10:32:05        REGISTRY: Unable to resolve type CurrencyId, it will fail on construction
I/flutter ( 2705): CONSOLE MESSAGE: 2021-08-01 10:32:05        API/INIT: Error: FATAL: Unable to initialize the API: createType(CurrencyId):: Cannot construct unknown type CurrencyId

Shortly after this it also throws the following error

I/flutter ( 2705): CONSOLE MESSAGE: 2021-08-01 10:32:58          API-WS: disconnected from wss://kusama-1.polkawallet.io:9944/: 1006:: Abnormal Closure

It never establishes a connection from this point on. I tried with 0.2.7 and 0.2.5

EDIT:
Turns out the address of the endpoint is wrong. Replacing it with any other address works fine (ex- wss://kusama.elara.patract.io)
