I have set up in the reproduce a couple of steps you can follow. Steps to Reproduce: 1. Clone https://github.com/DaanV2/Minecraft-bedrock-json-schemas 2. Observe the error thrown by `data\data 1.8.0.json` 3. Observe the error thrown by `data\data 1.8.5.json` 4. Observe the no errors by `data\data 1.8.6.json` **errors returned**  For the error in data 1.8.0.json: In `behaviour/entities/1.8.0/filters/clock_time.json` is the ref should be pointing to the `base_subject.json`  However, it ends up a folder too high. So I thought they might use a different home folder to resolve the path on. So I made version 1.8.5 which instead this reference: ```json "$ref": "./types/base_subject.json", ``` I used this references: ```json "$ref": "./filters/types/base_subject.json", ``` But this now returns the following: `.../1.8.5/filters/filters/types/base_subject.json'.` Which is a folder too deep. After this, I copied the files in question and made version 1.8.6, which now has no errors. As the files are where vscode expected them, but not where they actually should be.
