Inserting into arrays using asset patching doesn't work

[copygirl]

According to RFC 6902 linked in the 1.5.2 release post, inserting into arrays should be possible. This is kind of important if the order matters, which can be the case for block behaviors, for example

• If the target location specifies an array index, a new value is inserted into the array at the specified index.

Example patch

File: assets/carrycapacity/patches/carryable.json

[
  { file: "game:blocktypes/wood/generic/chest", op: "add", path: "/behaviors/0", value: {
    name: "Carryable",
    properties: {
      translation: [ 0.0625, 0, 0 ],
      rotation: [ 0, 180, 0 ],
    }
  } }
]

Workaround

Can replace the entire array for now:

[
  { file: "game:blocktypes/wood/generic/chest", op: "replace", path: "/behaviors", value: [
    { name: "Carryable", properties: {
      translation: [ 0.0625, 0, 0 ],
      rotation: [ 0, 180, 0 ],
    } },
    { name: "Container" },
    { name: "HorizontalOrientable" },
  ] }
]

Feel like fixing that @copygirl? It's this lib: https://github.com/tavis-software/Tavis.JsonPatch

It appears the "add" operator does not work at all. The following patch:

[
    { file: "game:blocktypes/clay/bowl", op: "replace", path: "/variantgroups/0/states", value: ["raw", "burned", "honey", "soup"] },
    { file: "game:blocktypes/clay/bowl", op: "add", path: "/shapeByType/*-soup", value: { base: "game:block/clay/bowl-ground" } },
    { file: "game:blocktypes/clay/bowl", op: "add", path: "/texturesByType/*-soup", value: { content: { base: "block/cauldron/cauldroninside" } } },
    { file: "game:blocktypes/clay/bowl", op: "add", path: "/nutritionPropsByType/*-soup", value: { 
        saturation: 400, 
        health: 1,
        eatenStack: { type: "block", code: "game:bowl-burned" }
    } },
]

produces the following errors:

Is this still an issue @copygirl?

[copygirl]

Nope, from what I know and have tested it should work now!
