getting codes from my db is not working. Any advice?

I changed my file name to diamonds but got the following console:

public/pages/masterPage.js: Missing semicolon. (5:6) 3 | $w.onReady(function () { 4 | // Write your code here > 5 | });npm install | ^ 6 |

Loading the code for the site. To debug this code, open masterPage.js in Developer Tools.

Loading the code for the test velo page. To debug this code, open n9x75.js in Developer Tools.

ReferenceError: wixData is not defined

test velo
Line 7
