WalletConnect Tendermint session chains are `null`, unable to activate

Session created with request:

  },

Scanned QR code with Keplr mobile wallet, which requested confirmation of selected chains as expected. Clicked to confirm.

Ran get_session for the session topic and got response:

  "mmrpc": "2.0",
  "result": {
    "session": {
      "topic": "ce98cae8561b21d14b59379d7b728fd74224241e3e5b44e515d4740d2de04b1b",

Chains being null does not match responses recorded in earlier testing, where it was

                    "chains": [
                        "cosmos:cosmoshub-4"
                    ],

Next, attempted activation as demonstrated by #2223 (comment)

{
    "userpass": "{{userpass}}",
    "mmrpc": "2.0",
    "method": "task::enable_tendermint::init",
    "params": {
        "ticker": "ATOM",
        "tokens_params": [
        ],
        "nodes": [
            {
                "url": "https://cosmos-rpc.alpha.komodo.earth/",
                "api_url": "https://cosmos-api.alpha.komodo.earth/",
                "grpc_url": "https://cosmos-grpc.alpha.komodo.earth/",
                "ws_url": "wss://cosmos-rpc.alpha.komodo.earth/websocket"
            },
            {
                "url": "https://cosmoshub.rpc.stakin-nodes.com/"
            }
        ],
        "activation_params": {
            "type": "WalletConnect",
            "params": {
                "session_topic": "ce98cae8561b21d14b59379d7b728fd74224241e3e5b44e515d4740d2de04b1b"
            }
        }
    }
}

Which returns:

{
    "mmrpc": "2.0",
    "result": {
        "status": "Error",
        "details": {
            "error": "Error on platform coin ATOM creation: Unable to fetch account for chain: Session Error: No active WalletConnect session found",
            "error_path": "lib.platform_coin_with_tokens.tendermint_with_assets_activation.lib",
            "error_trace": "lib:104] platform_coin_with_tokens:457] tendermint_with_assets_activation:233] lib:548]",
            "error_type": "PlatformCoinCreationError",
            "error_data": {
                "ticker": "ATOM",
                "error": "Unable to fetch account for chain: Session Error: No active WalletConnect session found"
            }
        }
    },
    "id": null
}

This response appears to be the same as if a non-existent session topic value is input.

Logs show

02 15:09:20, kdf_walletconnect:198] INFO WalletConnect: connecting…
02 15:09:21, kdf_walletconnect:208] INFO WalletConnect: online.

but nothing else to indicate any related errors or ops.

Unable to progress with further walletconnect testing until this is overcome.

Chains being null does not match responses #2223 (comment), where it was

i think u confused a request with a response in that link. i.e., KDf never used to return a non-null chains field with keplr.
the chains field (actually the whole parent namespaces field) is copied from what the wallet has provided.

i tried keplr and trustwallet. keplr seem to omit the chains field in their settle request. not sure if such a field is critical, but i will investigate if it has to do with the subsequent atom enabling error.

[mariocynicys]

i moved the other part regarding to non-consistent interface in the enable request to another issue: #2522

@smk762

i am not able to reproduce the activation error. i initialized a walletconnect connection using keplr (which returned chains: null like the one u have) and used the session topic from that session to enable ATOM (same request u have except session_topic ofc) and got a successful activation result:

{
    "mmrpc": "2.0",
    "result": {
        "status": "Ok",
        "details": {
            "ticker": "ATOM",
            "address": "cosmos1pw3...gvnw4",
            "current_block": 26457909,
            "balance": {
                "spendable": "0",
                "unspendable": "0"
            },
            "tokens_balances": {}
        }
    },
    "id": null
}

are u sure u typed the session_topic correctly?
