(Broken or incompatible)

[wary hatch]

Hi guys! I know that 1.21.9 changed the pack.mcmeta syntax and I've adapted mine to it, with the idea of keeping the back-compatibility.

{
  "pack": {
    "min_format": 69,
    "max_format": [69, 0],
    "description": "Working Backpacks\nUltroGhast",
    "pack_format": 55,
    "supported_formats": [
      48,
      69
    ]
  }
}```

Still, even though Misode’s generator and I agree that the syntax is correct, the game considers it incompatible.
The logs throw an error `Pack key supported_formats is deprecated starting from pack format 65. Remove supported_formats from your pack.mcmeta` (weren't old fields supposed to be just ignored by the new versions?) Even if I do, then the problem will be with pack_format.

What should I do? I really do care about back compatibility

Set the supported_formats max to 65

same result with same error, I've also tried with max to 64

for me it worked to set the supported formats to the same as the min and max format, in this cas you should set min_format to 48

this is one from my datapacks ```json
{
"pack": {
"min_format": 80,
"max_format": 88,
"pack_format": 80,
"supported_formats": [80, 88],
"description": "",
}
}
