how to connect to middleware?

I see that in cosmos error only if error field no empty - error. At minimum error field.

If result - success. But not 100% same text as result may come from Osmosis Hook.

So currently it will double mint with dozen of Cosmos chains in production.

Searched Osmosis and Cosmos repos.
