Error Message

AUR4109: Invalid rule execution result.

Description

This error occurs when the validation system receives an invalid value from a rule execution (for example a non-boolean/non-result value).

Common Scenarios

// ❌ Returning a string instead of a boolean/result
const badRule = () => 'yes' as any;

Solution

• Ensure rule implementations return true/false (or the expected validation result object), or a Promise of that value.

Troubleshooting

• Identify the rule that produced the invalid result and fix its return type.

• If you wrap/compose rules, ensure wrappers preserve the expected result type.
