Error when deploying to vercel, how to fix?

Question

GitHub

error  in ./src/main.js
Module not found: Error: Can't resolve 'graphql-request' in '/vercel/path0/src'
 ERROR  Error: Build failed with errors.
Error: Build failed with errors.

I get this error when deploying to vercel via vercel cli and via master branch on github. Please tell me how to fix?
I tried to reinstall dependencies, tried to clear information about git and upload it to the repository on a new one, tried to deploy separately without git.
