Error: [ graphql-let ] Never supposed to be here. Please make an issue on GitHub

Trying to set up graphql-let from the with-typescript-graphql example from NextJS

My config has a few layers to it so I'm not sure where to begin.

I'm using Lerna, but I don't think that's the issue, the app ran fine before I tried adding graphql-let, but I guess I'll add my config

// next.config.js

const withTM = require('next-transpile-modules')
const withLess = require('@zeit/next-less')
const withCSS = require('@zeit/next-css')
const withPlugins = require('next-compose-plugins')
const lessToJS = require('less-vars-to-js')
const fs = require('fs')
const path = require('path')

const themeVariables = lessToJS(fs.readFileSync(path.resolve('./assets/antd-custom.less'), 'utf8'))

// fix: prevents error when .less files are required by node
if (typeof require !== 'undefined') {
    require.extensions['.less'] = (file) => {}
}

const nextConfig = {
    dir: '.',
    distDir: '.next',
    webpack: (config, { isServer, ...options }) => {
        if (options.isServer) {
            const antStyles = /antd\/.*?\/style.*?/
            const origExternals = [...config.externals]
            config.externals = [
                (context, request, callback) => {
                    if (request.match(antStyles)) return callback()
                    if (typeof origExternals[0] === 'function') {
                        origExternals[0](context, request, callback)
                    } else {
                        callback()
                    }
                },
                ...(typeof origExternals[0] === 'function' ? [] : origExternals)
            ]

            config.module.rules.unshift({
                test: antStyles,
                use: 'null-loader'
            })
        }

        config.module.rules.push({
            test: /\.graphql$/,
            exclude: /node_modules/,
            use: [
                { loader: 'babel-loader', options: { presets: ['@babel/preset-typescript', '@babel/preset-react'] } },
                { loader: 'graphql-let/loader' }
            ]
        })

        config.module.rules.push({
            test: /\.graphqls$/,
            exclude: /node_modules/,
            use: ['graphql-let/schema/loader']
        })

        config.module.rules.push({
            test: /\.ya?ml$/,
            type: 'json',
            use: 'yaml-loader'
        })

        return config
    }
}

module.exports = withPlugins(
    [
        [withCSS],
        [
            withLess,
            {
                lessLoaderOptions: {
                    javascriptEnabled: true,
                    modifyVars: themeVariables
                }
            }
        ],
        [
            withTM,
            {
                transpileModules: ['@lywe/components', '@lywe/shared']
            }
        ]
    ],

The __generated__/lib is being created but not the .graphql.d.ts beside all GraphQL documents

Any ideas? I can provide more info if you need

[TaniaZaslon]

Have the same problem. Have any solution for this?

[piglovesyou]

Hi, thanks for reporting all this. If you can make a simple reproduction repo, that'll be more than helpful.

[j-mcgregor]

Not sure I can, I abandoned the project I had this error in a while ago, sorry

Hi, thanks for reporting all this. If you can make a simple reproduction repo, that'll be more than helpful.

@piglovesyou, Found differences between the data what being checked in this line https://github.com/piglovesyou/graphql-let/blob/db1fba47de9a4bafc1c7e18db955a09cdd8553c2/src/lib/dts.ts#L146

So in the end dtsContents is empty. And I receive this error "Never supposed to be here".

Platform: Windows.

My colleagues on Mac don't have this problem. Do you have an idea how to fix this?

[piglovesyou]

@TaniaZaslon Thank you so much for the clue, belatedly. Would you happen to have an idea of which GraphQL document causes it? It's great if we can have a sample project that reproduces the problem.
