# ERROR: Duplicate “graphql” modules cannot be used at the same time when starting code-first NextJS JSS application

I’m trying to create a new code-first NextJS demo using the JSS initializer for experimental purposes only:

However, running jss start always gives me this error:

I believe this error is caused by the graphql-let command in the package.json:

"bootstrap": "ts-node --project tsconfig.scripts.json scripts/bootstrap.ts && graphql-let"

I tried to add resolutions to this file but it didn’t help as npm was used instead of yarn.

My jss --version is: 20.0.3 and my node version is 16.15.1.

Does anyone have the same issue and do you know how to fix it?
