animo-mediator's Issues

Horizontal scalability

Hi, I want to know if this is horizontally scalable.

Can I have several instances running and load-balance between them? Is there any special setting I have to turn on?

Thank you in advance.

Confuse documentation regarding POSTGRESQL_DATABASE_URL

I struggled a bit to bring up the mediator in a docker container. I had the following error:

2023-06-06 07:22:23.612  INFO  [DIDComm Chat   WalletApi.initialize] Initializing wallet 'mediator' 
{
  id: 'mediator',
  key: '[*****]',
  storage: {
    type: 'postgres_storage',
    config: {
      url: 'postgres://postgres:postgres@postgres:5432/mediator',
      wallet_scheme: 'DatabasePerWallet'
    },
    credentials: '[*****]'
  }
}
2023-06-06 07:22:23.619  DEBUG [DIDComm Chat   IndySdkWallet._open] Wallet 'mediator' not found 
2023-06-06 07:22:23.619  DEBUG [DIDComm Chat   IndySdkWallet.createAndOpen] Creating wallet 'mediator' using SQLite storage 
2023-06-06 07:22:24.235  ERROR [DIDComm Chat   IndySdkWallet.createAndOpen] Error creating wallet 'mediator' 
{
  error: {
    stack: 'IndyError: WalletStorageError\n' +
      '    at Object.callback (/www/node_modules/indy-sdk/src/wrapIndyCallback.js:15:10)',
    name: 'IndyError',
    message: 'WalletStorageError',
    indyCode: 210,
    indyName: 'WalletStorageError',
    indyCurrentErrorJson: null
  },
  errorMessage: 'WalletStorageError'
}

After a bit of research, I endend up in another issue for indy-sdk which pointed to https://github.com/hyperledger/indy-sdk/blob/main/experimental/plugins/postgres_storage/src/postgres_storage.rs#L1085

There the connection url construction is displayed:

fn _admin_postgres_url(config: &PostgresConfig, credentials: &PostgresCredentials) -> String {
        let mut url_base = "postgresql://".to_owned();

        match credentials.admin_account {
            Some(ref account) =>url_base.push_str(&utf8_percent_encode(&account[..], &NON_ALPHANUMERIC).to_string()),
            None => ()
        }
        url_base.push_str(":");
        match credentials.admin_password {
            Some(ref password) => url_base.push_str(&utf8_percent_encode(&password[..], &NON_ALPHANUMERIC).to_string()),
            None => ()
        }
        url_base.push_str("@");
        url_base.push_str(&config.url[..]);
        url_base.push_str("/");
        url_base.push_str(_POSTGRES_DB);
        url_base
    }

So the POSTGRESQL_DATABASE_URL should be postgres:5432 as per your docker example.

"Timeout has occurred" when trying to use the mediator

I can issue a credential locally using the mediator.dev.animo.id invitation url.

But when I run yarn dev to get a mediator using this repo, I can't get the new ngrok invitation url to work.

The yarn dev output looks promising:

Visiting in my browser: https://REDACTED.ngrok.app/invite?oob=VALID_LOOKING_ACCESS_TOKEN also looks promising. I get Missing or invalid _oobid which is the same thing what I see if I visit the mediator.dev.animo.id invitation url.

After running my issue credential script locally using the new ngrok url, it gets stuck at the start of the mediator connection attempt:

Any advice?

Add a CHANGELOG.md

Would be awesome if we could get a CHANGELOG file to keep track of the changes being made

Add a /health endpoint

It could be nice to have a /health enpoint in order to be able to monitor the status of the mediator.

Thanks in avance and thanks for your great work.
