Property {$offset} does not exist.

Error message

Property {$offset} does not exist.

What it means

ModelInfo is a read-only Arrayable DTO exposing introspection data about a model (class, table, attributes, relations, etc.). offsetGet() checks property_exists($this, $offset) and throws InvalidArgumentException if the offset is not one of the known public properties, because there is nothing meaningful to return.

Solutions

1. Use only documented property keys (class, database, table, policy, attributes, relations, events, observers, collection, builder, resource).
2. Use offsetExists($key) or isset($info[$key]) before accessing.
3. Use $info->toArray() and read from the resulting array if you need flexible key access.

Example fix

// before
$info['attributez']; // typo

// after
$info['attributes'];
// or guarded:
if (isset($info['attributes'])) { ... }

if (! isset($info[$offset])) {
    throw new \InvalidArgumentException("Unknown ModelInfo key: {$offset}");
}
return $info[$offset];

function infoHas(\Illuminate\Database\Eloquent\ModelInfo $info, string $key): bool {
    return isset($info[$key]);
}

When it happens

Trigger: Accessing an unknown key via array syntax on a ModelInfo instance returned by Model::observe()/introspection helpers, e.g. $info['nonexistent'] or $info['invalidKey'].

Common situations: Iterating or dynamic key access over ModelInfo with a typo'd or unsupported property name; assuming ModelInfo exposes arbitrary model attributes (it only exposes fixed introspection fields).
