Current Behavior

Fatal error: Allowed memory size of 4294967296 bytes exhausted (tried to allocate 20480 bytes) in /app/Data/Temporary/Development/SubContextDocker/Cache/Code/Flow_Object_Classes/Neos_Neos_Fusion_NodeUriImplementation.php on line 162

Expected Behavior

An exception log file instead of the memory error.

Steps To Reproduce

There are different ways to trigger the error, I use the following example:

First you need a content element of type Neos.Neos:Plugin which uses Neos.Neos:NodeUri.

prototype(Flowpack.Neos.FrontendLogin:LoginForm) < prototype(Neos.Neos:Plugin) {
        …
	redirectAfterLoginUri = Neos.Neos:NodeUri {
  		node = ${q(node).property('redirectAfterLogin')}
	}
       …
}

Note that redirectAfterLogin has no default value thus may be null.

Environment

- Flow: 9.0 and 9.1
- Neos: 9.0 and 9.1
- PHP: 8.3

Anything else?

When redirectAfterLogin is null, NodeUriImplementation::evaluate() called in PluginImplementation::evaluate() throws.

Since the NodeUri uses @exceptionHandler = 'Neos\\Fusion\\Core\\ExceptionHandlers\\AbsorbingHandler' the exception is ignored and a log is generated by calling Debugger::getObjectSnippetPlaintext(object).

At some point, object is an instance of PluginImplementation which implement __toString(). Hence, __toString() is used to create the log, but it looks as follows:

/**
 * @return string
 */
public function __toString()
{
    return $this->evaluate();
}

This causes an endless loop rendering the stack trace until the memory limit is reached.
