Pine studies fail with "Can't parse pine": pine-facade translate no longer returns ilTemplate #354
Description
Since 2026-10-27 (between ~08:00 and ~12:00 UTC), pine-facade/translate no longer returns result.ilTemplate. Every Pine study built from it is created with no script, and the chart server answers study_error "Can't parse pine". This affects built-in (STD;RSI), public and private (USER;…) scripts alike.
Where the compiled script went: it is now sent only as the defval of the hidden text input (name: "ILScript") in result.metaInfo.inputs. The value starts with the usual bmI9Ks46_ prefix. pineId and pineVersion still come with an empty defval.
curl -s 'https://pine-facade.tradingview.com/pine-facade/translate/STD%3BRSI/last' \
| jq '{keys: (.result | keys), text: (.result.metaInfo.inputs[] | select(.id == "text") | .defval[0:20])}'
# {"keys": ["metaInfo"], "text": "bmI9Ks46_..."}Affected code: parseIndicatorDefinition in the npm 4.x builds (dist/http/indicators.js, script: result.ilTemplate), and getIndicator in src/miscRequests.js on main (script: data.result.ilTemplate). parseInputs skips the text input, so PineIndicator.toStudyInputs() sends text: undefined. This happens on 4.0.0, 4.0.1 and 4.1.0.
Workaround we use: take the script from result.ilTemplate when it is present, else from the text input's defval, and pass that as ilTemplate to parseIndicatorDefinition:
function scriptFromTranslate(result) {
if (result.ilTemplate) return result.ilTemplate;
const text = result.metaInfo.inputs?.find((input) => input.id === 'text')?.defval;
if (typeof text === 'string' && text) return text;
throw new Error('no compiled script: neither result.ilTemplate nor the "text" input defval');
}
const indicator = parseIndicatorDefinition({ ...result, ilTemplate: scriptFromTranslate(result) }, id, version);With this change, studies work again for STD;RSI, private scripts and strategies (backtest reports).

I had the same issue and the workaround is in the right direction.
fix: read the compiled Pine script from the "text" input
Fix "Can't parse pine": read the compiled script from its new location (

Update: TradingView moved the compiled script again. Since about 30 Oct 2026, the
textinput'sdefvalis empty and the script lives inresult.metaInfo.defaults.inputs.text, so the workaround above stopped working.Fixed in #355, published as
4.1.1-beta.0(npm i @mathieuc/tradingview@beta). It reads all three locations (ilTemplate, thetextinput,metaInfo.defaults.inputs.text). Verified live with an authenticated session:STD;RSIand a privateUSER;…indicator return data again.On 3.x (
src/miscRequests.js,getIndicator), the equivalent patch is:
