I have https://github.com/gorules/jdm-editor installed in my project. One of its dependencies is immer. When I run tsc --noEmit I get this TS6133 error:

npm run type-check

> [email protected] type-check
> tsc --noEmit

node_modules/immer/src/utils/common.ts:207:33 - error TS6133: 'key' is declared but its value is never read.

207   Object.entries(obj).forEach(([key, value]) => freeze(value, true))
                                    ~~~

Found 1 error in node_modules/immer/src/utils/common.ts:207

From what I’ve read, this is because it’s a transitive dependency so TypeScript is type-checking it as part of the dependency graph for jdm-editor.

If I install immer on its own, I have no TS error, which is why I think this has to do with it being a transitive dependency. How can I get TS to ignore this issue?

Here’s my tsconfig.json:

{
  "compilerOptions": {
    "allowJs": true,
    "allowSyntheticDefaultImports": true,
    "alwaysStrict": true,
    "declaration": true,
    "emitDecoratorMetadata": true,
    "esModuleInterop": true,
    "experimentalDecorators": true,
    "forceConsistentCasingInFileNames": true,
    "importHelpers": true,
    "incremental": true,
    "isolatedModules": true,
    "jsx": "react-jsx",
    "lib": ["dom", "dom.iterable", "esnext"],
    "module": "esnext",
    "noFallthroughCasesInSwitch": true,
    "noImplicitAny": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "moduleResolution": "node",
    "noEmit": true,
    "removeComments": true,
    "resolveJsonModule": true,
    "skipLibCheck": true,
    "sourceMap": true,
    "strict": true,
    "strictBindCallApply": false,
    "strictNullChecks": true,
    "target": "esnext",

  },
  "exclude": ["./node_modules", "../typings"],
  "include": ["./src", "./vite.config.ts", "./jest.config.ts"]
}

Tried skipLibCheck false and true, with no change. Tried installing immer on its own and verified that it works fine solo. Tried pinning version of immer.
