unable to import my module from 'backend/data'

Through Velo development screen, that simple line of of code:

import { projectSQL } from ‘backend/data’ ;

Is providing this message:

“‘projectSQL’ is declared but its value is never read.
Cannot find module ‘backend/data’ or its corresponding type declarations.”

Also at the run time, I received this one:

Cannot find module ‘backend/data’ in ‘public/pages/on68k.js’

Can somebody give me any clue

Are you importing it to the frontend? If you’re, make sure it is in a jsw file and write from ‘backend/data.jsw’;

Yes I do, as shown in the picture

from 'backend/data .jsw ';
