E4001 error

Manifest is not valid JSON

area: manifest (x4xxx)
fails the build: yes

wowlua.json is not valid JSON. The manifest is strict JSON: no comments, no trailing commas, keys and strings in double quotes. Nothing else in the package is checked until the manifest parses.

The message gives the position of the first problem. Remove the trailing comma or comment, or quote the key. An editor that knows the manifest's $schema shows these mistakes as you type.
