Property not found

Error message

Property not found

What it means

BeanInjector.getObject looks up the named metadata-injection property in BeanInjectionInfo; if the property name is not a registered injection property of the target class it throws RuntimeException('Property not found'). Used mainly by tests/debug code to read a field value by injection property name.

Solutions

1. List valid names via new BeanInjectionInfo(rootClass).getProperties().keySet() and use one exactly
2. Check the target field has an @Injection annotation with the name being requested
3. Ensure the BeanInjector was built for the same class as the root object

Example fix

// before
injector.getObject(meta, "feildName");
// after
injector.getObject(meta, "fieldName"); // exact @Injection name

Set<String> valid = new BeanInjectionInfo(root.getClass()).getProperties().keySet();
if (!valid.contains(propName)) throw new IllegalArgumentException(propName + " not in " + valid);

try { return injector.getObject(meta, propName); }
catch (RuntimeException e) { log.warn("Unknown injection property " + propName); return null; }

When it happens

Trigger: Calling beanInjector.getObject(root, propName) where propName is not a key in info.getProperties() — i.e. the name is misspelled, not annotated with @Injection, or belongs to a different class than the BeanInjector was constructed for.

Common situations: Passing a getter-style or display name instead of the injection name; target plugin class updated and the property removed/renamed; using the wrong BeanInjectionInfo for the object.
