Specifying the size of a target in post effect shaders fails

As of 24w33a, the "targets" field of post shaders is an object, instead of an array of objects/strings. It works correctly when the name of the target is mapped to an empty object. However having the object contain fields "width" and "height" fails to load the shader file.

Steps to Reproduce:

1. Create a resource pack in version 24w34a (pack format 36)

2. Copy the vanilla file assets/minecraft/post_effect/transparency.json

3. In the "targets" field, write

   {
           "final": {},
           "potato": {
               "width": 16, "height": 16
           }
   }

4. Load the resource pack with fabulous graphics

Observed Results:
The resource pack fails loading, and the game logs raise this error:

[^deobf_latest.log]

Expected Results:
Since this is the vanilla file, in which we specified an unused target (the same as the example from the article, the game should not output an error.

Notes:
From what I understood reading the output logs, it seems the json interpreter struggles with the new syntax...

Attachment
The joined zip file is a resource packs, for 24w34a.It modifies the

assets/minecraft/post_effect/transparency.json

, specifically adding a target in the post effect shader. I made sure to use the same syntax as in the snapshot article to demonstrate the bug.
