npm ERR! missing script: json: - npm

Question

I'm getting this error when I run npm run json: server.
npm ERR! missing script: json:
when I open the log file, this is what it says:

My package.json has the following
{
"name": "jsonserver",
"version": "1.0.0",
"description": "Fake REST API for testing",
"main": "index.js",
"scripts": {
"json:server": "json-server --watch db.json"
},
"author": "",
"license": "ISC",
"dependencies": {
"json-server": "^0.12.1"
}
}
I did not modify anything since it's last successful run. When I was starting to work the following day, suddenly the error.
TIA.

Rename the "json:server" in scripts to any of the JSON verified characters.
: are generally used to separate key-value pair.
Even in the log it's pointing out to the same (see verbose line 7).
7 verbose argv "C:\Program Files\nodejs\node.exe" "C:\Users\IanP\AppData\Roaming\npm\node_modules\npm\bin\npm-cli.js" "run" "json:" "server"
So, it would be good idea to replace "json:server" with "json-server" or using camel-Case insted like "jsonServer".
Hope this helps.
