JavaScript execution error: {ex.Message}

Error message

JavaScript execution error: {ex.Message}

What it means

Wraps a ClearScript ScriptEngineException thrown during engine.Execute(javaScript). ScriptEngineException fires on JS syntax errors, runtime errors (TypeError, ReferenceError), or host-call failures. The wrapper flattens it into a generic System.Exception carrying the engine's message and inner exception.

Solutions

1. Read ex.Message (and the inner ScriptEngineException.ErrorDetails if available) to find the JS line/column.
2. Validate/lint the JS before passing it to IsMatchJavaScript.
3. Wrap risky host interactions in try/catch inside the JS.
4. Provide a documented set of available globals (ArtifactStat) and a template.

Example fix

// before
await Task.Run(() => engine.Execute(javaScript));
catch (ScriptEngineException ex) { throw new Exception($"JavaScript execution error: {ex.Message}", ex); }
// after - surface line info
catch (ScriptEngineException ex)
{
    throw new Exception($"JavaScript execution error: {ex.Message}\n{ex.ErrorDetails}", ex);
}

try { Jint.Engine e = new(); e.Execute(js); } catch { /* reject before passing to ClearScript */ }

try { await Task.Run(() => engine.Execute(javaScript)); }
catch (ScriptEngineException ex) { throw new Exception($"JavaScript execution error: {ex.ErrorDetails ?? ex.Message}", ex); }

When it happens

Trigger: JS has a syntax error (missing brace, bad token); references an undefined variable; calls a host method that throws; uses unsupported ES features for the V8 version bundled with ClearScript.

Common situations: User-typed JS with typos; script assumes a global (like 'console' or 'require') not provided by ClearScript; version drift in the ClearScript/V8 engine changing supported syntax.
