TypeError: func is not a function - npm

See original GitHub issue

I was using graphql-code-generator successfully, but now when I run npm run codegen, I’m getting func is not a function error. As suggested in #3256, I removed node_modules, package-lock.json and npm install from scratch, but it didn’t help.

I added a sandbox with same dependencies here: https://codesandbox.io/s/silly-haibt-3u7sq

Unfortunately, I cannot reproduce error there. Please advise.

✖ types/types.ts
    TypeError: func is not a function
        at .../node_modules/@graphql-codegen/visitor-plugin-common/index.cjs.js:259:19

Error message points to convertNameParts function:

function convertNameParts(str, func, removeUnderscore = false) {
    if (removeUnderscore) {
        return func(str);
    }
    return str
        .split('_')
        .map(s => func(s))
        .join('_');
}

@ardatan, I updated the sandbox and problem seems to be solved. Case may be closed. Thanks.

Using below I’m getting same error with “npm install” from scratch. (yarn is still OK)
