code execution failed!

Error message

code execution failed!

What it means

In the same generated CodeNode helper, if all retry attempts to execute the code node fail (after retries with retryIntervalMs sleeps), the function returns an optional defaultValue; when no default is configured it throws RuntimeException('code execution failed!'). It signals persistent failure of user-supplied code execution.

Solutions

1. Fix the underlying exception in the code node script — inspect the cause chain of this RuntimeException.
2. Configure a defaultValue on the code node so the workflow can continue when execution fails.
3. Increase retry count / retryIntervalMs on the node if failures are transient.

Example fix

// before
throw new RuntimeException("code execution failed!");
// after  (node config)
retryCount: 3, retryIntervalMs: 500, defaultValue: Map.of("output", "")  // or fix the script bug

if (node.getDefaultValue() == null && node.getRetryCount() == 0)
    warn("Code node has no default and no retries — failures will abort the workflow");

try { codeFn.apply(state); } catch (RuntimeException e) { if ("code execution failed!".equals(e.getMessage())) return defaultOrEmptyResult(); throw e; }

When it happens

Trigger: assistMethodCode-generated Function: codeNodeAction.apply(state) throws on every attempt (retries exhausted) and defaultValue == null at that call site.

Common situations: User script has a runtime bug (NPE, syntax-level runtime failure); script times out or depends on unavailable services; state lacks inputs the script expects.
