Bug Report

I use extractor to get data from LLM but it always returns Err(Nodata). Manually using agent to get json deserialized to struct works fine.

Reproduction

use rig::providers::openai;
use schemars::JsonSchema;

#[derive(Debug, serde::Serialize, serde::Deserialize, schemars::JsonSchema)]
pub struct VideoMetadata {
    pub title: String,
    pub season: Option<u32>,
    pub episode: Option<u32>,
}

#[tokio::main]
async fn main() {
   // use https://www.volcengine.com service
    let client = openai::Client::from_url(
        "TOKEN",
        "https://ark.cn-beijing.volces.com/api/v3",
    );

  // use deekseek-v3 or other model not work too
    let extractor = client
        .extractor::<VideoMetadata>("deepseek-v3-241226")
        .preamble("你是一个专业的视频元数据提取助手。你的任务是从视频文件名中提取标题、季数和集数。请分析文件名并提取这些信息。")
        .build();

    let filename =
        "[Airota&VCB-Studio] Yuru Camp Season 3 [01][Ma10p_1080p][x265_flac].mkv".to_string();

    let result = extractor.extract(&filename).await;
    println!("{:?}", result)
}

cargo.toml

[package]
name = "bug-report"
version = "0.1.0"
edition = "2024"

[dependencies]
rig-core = "0.9.1"
schemars = "0.8.22"
serde = { version = "1.0.219", features = ["derive"] }
serde_json = "1.0.140"
tokio = { version = "1.44.1", features = ["full", "macros", "rt-multi-thread"] }

Expected behavior

extractor can extract correctly

RIG-700 bug: Cant't extract data from extractor

Hi, can you provide a URL for the documentation of the service you are using? This appears to be an issue related to the API and not rig's extract API

[deep60]

Your API key has an error; it needs to be set as an environment variable to use the extractor.

I used a third-party deepseek-v3-chat model service, which provides an openai compatible API method

let extractor = client
        .extractor::<VideoMetadata>("deepseek-v3-241226")
...

The client has been initialized with the API KEY. Does the Extractor obtained in this way still not work?

Is there any URL for an API reference? I suspect the root cause might be that the API is not actually 100% compliant.

I cannot reproduce as I'm unable to obtain an api key

[locez]

Maybe you could tell me how to debug this, add some output and I can try to fix it by myself

[locez]

I don’t have time to try it now, so I plan to close this issue temporarily. I have recently learned more ways to build agents, but that is based on Python. In the future, I will come back and try to use Rig to build related applications, but it should not be my previous crude usage.
