Type errors with strict rule

See original GitHub issue

We are running into issues with typescript throwing errors when running with the strict: true option in tsconfig.json.

This is the output from tsc:

I’ve tried to override these myself, to get typescript to stop complaining, with no luck (yet) since the types are part of the library.

Our tsconfig:

{
    "compilerOptions": {
        "allowJs": true,
        "allowSyntheticDefaultImports": true,
        "baseUrl": "./client",
        "experimentalDecorators": true,
        "jsx": "react",
        "module": "commonjs",
        "noEmit": true,
        "noImplicitAny": true,
        "pretty": true,
        "strict": true,
        "target": "es2019",
        "paths": {
            "generated/*": ["../generated/*.ts"]
        }
    },
    "include": ["index.ts"]
}

This is with Typescript 4.2.3 but I’ve tried it with the 4.3.5 as well
