VaultSharp.Core.VaultApiException : {"errors":["invalid role ID"]}

Hello,

We are trying to use key-value secrets like this -

var authMethod = new AppRoleAuthMethodInfo("...",
                "....");

            var vaultClientSettings =
                new VaultClientSettings("...", authMethod);

            var vaultClient = new VaultClient(vaultClientSettings);

            var value = new Dictionary<string, object> { { "key1", "val1" }, { "key2", 2 } };
            await vaultClient.V1.Secrets.KeyValue.V1.WriteSecretAsync("secretPath", value);

            var kv1Secret = await vaultClient.V1.Secrets.KeyValue.V1.ReadSecretAsync("secretPath");
            var dataDictionary = kv1Secret.Data;

And We get VaultSharp.Core.VaultApiException : {“errors”:[“invalid role ID”]} with above. Please help
