Market becomes empty after I added custom entries in Market.json config file. But without custom entries, everything loads fine. I'm using 1.12.2 version.

IIRC there is a link to an example file on the readme.

Errors loading the registry are printed in both chat and logs.

I already tried that and it didn't work, But I thought that link example is for datapack, and not Market.json file in the config folder?

Nothing showed up in the chat but here's my latest log.

latest.log

[22:46:33] [Client thread/ERROR]: Failed to load Market registry: com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Expected name at line 52 column 2 path $.custom entries.minecraft:stone

How do I fix that error?

Post your full market config, the screenshot is outdated since there's no mentioning of minecraft:stone in there, yet the error is complaining about it.

There's an extra comma at the end that shouldn't be there.
