Internal error (failed to find matching key for verification) when using java sdk on `dev` environment

When I try to use java sdk to make a simple call to Fiskaly api on dev environment

    val apiKey = "API_KEY"
    val apiSecret = "API_SECRET"
    val client = FiskalyHttpClient(apiKey, apiSecret, "https://sign.fiskaly.dev/api/v2")
    println(client.request("GET", "/tss"))

I get exception:

Exception in thread "main" FiskalyClientException{ Code=-32603, Message=Internal error, Data="failed to find matching key for verification: failed to find matching key for key ID \"GZzxbuN8ZCafnK1xRWe08caWgXH9x1OMfOGWyyjrpS4\" in key set"}

I'm trying with the latest 1.2.200 java sdk (tried on both Android and MacOS).
