Currently the nullsafe operator doesn't work with array index paths. However, this is not obvious at first sinceTHROW_ON_INVALID_PROPERTY_PATH is not enabled by default:

useSymfony\Component\PropertyAccess\PropertyAccessor;var_dump((newPropertyAccessor())->getValue([],'[foo]'));// NULLvar_dump((newPropertyAccessor())->getValue([],'[foo?]'));// NULLvar_dump((newPropertyAccessor(throw: PropertyAccessor::THROW_ON_INVALID_INDEX))->getValue([],'[foo]'));// Cannot read index "foo" while trying to traverse path "[foo]".var_dump((newPropertyAccessor(throw: PropertyAccessor::THROW_ON_INVALID_INDEX))->getValue([],'[foo?]'));// Cannot read index "foo" while trying to traverse path "[foo]". (THIS IS WRONG, SHOULD BE NULL)
