UNKNOWN_INFORMEES","cause"

Hello,
Recently, I deployed Testnet node using docker-compose approach, setting the Auth0, configure DA Utility UI. However, when I try to Request Provider Service from UI I got this error:

UNKNOWN_INFORMEES","cause":"The participant is not connected to any synchronizer where the given informees are known.

Any hints is appreciated.

Hi @wshbair , kindly refer on this link for the error code description: UNKNOWN_INFORMEES.

Thanks for the link,
Still how I can Check the list of submitted informees?

Think of “informees” as who got told about your transaction.
After you submit a command and get its transaction ID, fetch that transaction’s tree from the Ledger API; every event in the tree lists the witness_parties (who saw that event). Just collect all the witness_parties from all events and take the unique set, that’s your list of informees.

This is my command

{

    {
      "CreateCommand": {
        "templateId": "#utility-registry-app-v0:Utility.Registry.App.V0.Service.Provider:ProviderServiceRequest",

        }
      }
    }

}

This is the response I got:

looks like the operator is not know, but how to fix ?

You’re hitting UNKNOWN_INFORMEES because the participant you’re submitting to isn’t connected to any synchronizer (domain) where one of the stakeholders/observers of the new contract, here, operator = auth0_007c65…::1220d2d7…, is known. For a Create, the informees are the signatories and observers of the created contract; every informee must be known on (i.e., allocated/hosted or at least discoverable via topology on) some synchronizer the submitting participant is connected to.

So how i can fix this ?

8

Use ListKnownParties/GetParties on that participant to confirm both the actAs provider and the operator are listed; if the operator is missing, either allocate/import it on this participant’s synchronizer or connect this participant to the synchronizer that hosts the operator and ensure hosting/topology is published.

Thanks for your hint, it really help :handshake:
I found the given operator exist in the Devnet while my node run on Testnet. So I changed the the config as follows:
UTILITY_APP_UTILITY_BACKEND_URL="``https://api.utilities.digitalasset-staging.com``"
