Error appears after running npm run build

[ras-24]

An error appears during the initial installation at the npm run build stage. I use Windows 10 PC with Nodejs v14.21.3

Steps I do :

1. git clone https://github.com/canove/whaticket-community.git
2. cd whaticket-community\backend
3. copy .env.example .env
4. Modify .env file like below :

   
   NODE_ENV=
   BACKEND_URL=http://localhost
   FRONTEND_URL=http://localhost:3000
   PROXY_PORT=8080
   PORT=8080

DB_DIALECT= DB_HOST=localhost DB_USER=root DB_PASS= DB_NAME=whaticket

JWT_SECRET=54616516516516851751651 JWT_REFRESH_SECRET=56126168175165161564165

5. npm install
6. npm run build
After running `npm run build` i got error below :

E:\Programming\Javascript\whaticket-community\backend>npm run build

How to fix this error?

looks like it doesnt support the typescript version on package.json anymore. https://github.com/DefinitelyTyped/DefinitelyTyped/issues/69932

How can i back to previous version?

In my case, i solved it by bumping typescript version to "typescript": "4.7.3" in the package.json file
