'Swaggest\\JsonDiff\\Exception' with message 'Key not found: key'

[allentsai]

Hello, I'm getting the following error:

Exception/Stack Trace:

PHP Fatal error:  Uncaught exception 'Swaggest\\JsonDiff\\Exception' with message 
'Invalid key for array operation' in /usr/local/src/placelocal/vendor/swaggest/json-diff/src/JsonPointer.php:120
Stack trace:
#0 /usr/local/src/placelocal/vendor/swaggest/json-diff/src/JsonPatch.php(121): Swaggest\\JsonDiff\\JsonPointer::add(Object(stdClass), Array, 'missing value', false)

#2 {main}
  thrown in /usr/local/src/placelocal/vendor/swaggest/json-diff/src/JsonPointer.php on line 120

Using php5.6, v3.4.0

Test Code:

$old = [
    "key" => "diffvalue",
    "nestedKey" => ["nestedKey" => "nesteddiffValue"],
    "unchanged" => "value",
    "new key" => "new value",
    "new array" => ["new value3", "new value2"],
    "notMissingKey" => [],
    "appendKey" => ["value1", "value2"]
];
$new = [
    "key" => "value",
    "nestedKey" => ["nestedKey2" => "nestedValue"],
    "unchanged" => "value",
    "missingKey" => ["missingkey's child key" => "missing value"],
    "notMissingKey" => ["nmk:missingkey" => "missing value", "nmk:missingkey2" => "missing value 2"],
    "appendKey" => ["value1"]
];

$diff = new \Swaggest\JsonDiff\JsonDiff(json_decode(json_encode($old)), json_decode(json_encode($new)));
$patch = $diff->getPatch();

$test = json_decode(json_encode($old));
$patch->apply($test);

The problem seems to be that "notMissingKey" => [], which is treated as an array in the patch, and becomes an object later ["nmk:missingkey" => "missing value", "nmk:missingkey2" => "missing value 2"]
