I'm a full-stack developer, working on various apps and projects.
And I'm constantly sharing articles related to development.

I used the condenser_api.get_discussions_by_feedAPI to get the Feed list of My Friends from the Steemit API.
However, I got an error like below.

{
    "jsonrpc":"2.0",
    "id":1,
    "error":{
        "code":-32603,
        "message":"Internal Error",
        "data":{
            "error_id":"da9bad15-8d96-4c65-a3e0-7ba44322798d",
            "jussi_request_id":"000849412037747723"
        }
    }
}

I remember this API working well in the past.
You can read about it in the following articles: [Flutter] Mobile App Development with Flutter - Implementing a Steemit Feed

This error prevented us from continuing development. So I looked at what APIs the other services were calling.
The steemit condenser and UPVU , ECBlog services were all using the bridge.get_account_posts API. However I couldn't find that API in the Steem API documentation.

Since there was no API documentation, I developed it by referring to the condenser source code.

Below is the Dart code to parse the bridge.get_account_posts result.
