# UI_SCHEMA_NOT_JSON

The Schema Builder's `ui-schema.json` is not valid JSON.

## Cause

The Schema Builder's `ui-schema.json` is not valid JSON.

The Schema Builder writes `ui-schema.json` as JSON. The file could not be parsed, usually after a hand edit or a merge conflict left in it, so none of its entities could be read.

## Fix

* Fix the JSON at the position the Why line names, or resolve the merge conflict in the file.
* Or restore the file from version control, for example `git checkout -- ui-schema.json`.

## Example

```text
✗ ui-schema.json is not valid JSON.
  Why:  Unexpected token '}', "{ "collections": [ }" is not valid JSON
  Next: Fix the JSON at the position named, or restore `ui-schema.json` from version control, then run the command again.
