If I follow the steps of adding Graph Client to a fresh install of Next.js with TypeScript, running npx graphclient build yields the following output:

💡 GraphClient Cleaning existing artifacts
💡 GraphClient Reading the configuration
💡 GraphClient Generating the unified schema
💥 GraphClient - uniswapv2 Failed to generate the schema Error: Failed to fetch introspection from https://api.thegraph.com/subgraphs/name/uniswap/uniswap-v2: error TS5095: Option 'bundler' can only be used when 'module' is set to 'es2015' or later.

The error can be fixed with changing "moduleResolution" from "bundler" to "node". That being said, this might not be obvious for a lot of developers. Is it possible to make Graph Client work with "moduleResolution": "bundler"?
