👍 Thank you

Hint: depending on where and how the nodes are fetched from, the type would be
Neos\ContentRepository\Core\Projection\ContentGraph\Nodes instead of array<...Node>

Thank you for your PR

Could you also adjust the composer.json?

    "require": {
        "neos/neos": "^9",
        "carbon/eel": "^2.0"
    },

@jonnitto do you have more context how preloadNodes and prerenderNodes might be fetched? We might need to change the proptype definition for those two because I think in most cases we probably get Neos\ContentRepository\Core\Projection\ContentGraph\Nodes. I can also check that in project code as I remember already stumbling upon this case a while ago.

Thx for the reminder @nezaniel.

@ahaeslich Is Neos\ContentRepository\Core\Projection\ContentGraph\Nodes loop-able with Neos.Fusion:Loop?

Or is there a way to convert Neos\ContentRepository\Core\Projection\ContentGraph\Nodes into an array with Nodes? Ad the Fusion:Loop uses ${Array.unique()} to make the nodes unique…
