Module not found: Error: Can't resolve 'class-validator'

I followed the instructions to Customize the site

And I am getting the following error:

ERROR in ./node_modules/routing-controllers/esm2015/ActionParameterHandler.js

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Note : I tried from both Windows and WSL . It's same result.

Hi @thinkgandhi, I just double checked, but it looks to be working fine. Did you do npm install at /catalog folder?
