Fails when removing multiple elements from array

[aaproducto]

When you remove more than one element from an array, it breaks.

A test case:

source

[{"name":"a"},{"name":"b"},{"name":"c"}]

target:

[{"name":"a"}]

Error:

Uncaught exception 'Swaggest\JsonDiff\Exception' with message 'Key not found: 2' in /var/www/alquilerargentina/vendor/swaggest/json-diff/src/JsonPointer.php:185

note: pretty similar to this one java-json-tools/json-patch#11

There is indeed a misbehaving, when I apply

[{"op":"remove","path":"/0"},{"op":"remove","path":"/2"}]

I get {"1":{"name":"b"}} instead of [{"name":"b"}]. I'll fix that.

But back to your error, I was unable to reproduce it.

swaggest/json-diff produces

[
    {
        "value": "a",
        "op": "test",
        "path": "/0/name"
    },
    {
        "value": "b",
        "op": "replace",
        "path": "/0/name"
    },
    {
        "op": "remove",
        "path": "/1"
    },
    {
        "op": "remove",
        "path": "/2"
    }
]

from your two jsons, which maybe isn't very short, but applies without error.

Could you share exact code that produced exception?

[aaproducto]

This is the code that produced the error:

$originalJson = '[{"name":"a"},{"name":"b"},{"name":"c"}]';
$newJson = '[{"name":"b"}]';
$diff = new JsonDiff(json_decode($originalJson), json_decode($newJson));

//we need to serialize the patch to send it to AWS SQS
$patchJson = json_decode( json_encode($diff->getPatch()->jsonSerialize()), true );

$original = json_decode($originalJson);
$patch = JsonPatch::import($patchJson);
$patch->apply($original);

This is a simple test to reproduce an error that we having in our project.
By the way the version i am using is the v2.0.1

Should be fixed with v2.0.2
