Token sem value

Error message

Token sem value

What it means

Thrown in fetch_access_token when the Twitch playback access token JSON has a signature but no string "value" field. Both signature and value are required to build the authenticated playback URL (AccessToken struct), so the library fails fast with this Portuguese message ("Token without value").

Solutions

1. Log the raw token_obj JSON to see actual keys
2. Validate the clip exists and is not restricted before requesting a token
3. Update parsing to match the current Twitch GQL schema
4. Retry once — intermittent Twitch responses can omit fields

Example fix

// before
let value = token_obj.get("value").and_then(|v| v.as_str()).ok_or_else(|| anyhow!("Token sem value"))?.to_string();
// after
let value = token_obj.get("value")
    .and_then(|v| v.as_str())
    .ok_or_else(|| anyhow!("Token sem value; response keys: {:?}", token_obj.as_object().map(|o| o.keys().collect::<Vec<_>>())))?;
.to_string();

fn has_valid_token(obj: &serde_json::Value) -> bool {
    obj.get("signature").and_then(|v| v.as_str()).is_some()
        && obj.get("value").and_then(|v| v.as_str()).is_some()
}

fn is_string_field(v: &serde_json::Value, key: &str) -> Option<&str> {
    v.get(key).and_then(|x| x.as_str())
}

When it happens

Trigger: Twitch's GQL PlaybackAccessToken response object contains signature but the "value" key is missing, null, or not a string.

Common situations: Twitch schema changes; partial/degraded API responses; clip restricted so Twitch returns a truncated token object.
