Error: Module '@types/cookie/index' has no default export. ts(1192)
Error: Property 'userid' comes from an index signature, so it must be accessed with ['userid']. ts(4111)

Strictest tsconfig from https://github.com/tsconfig/bases/blob/27f9097a02f960e351d69bca8dd4c7581d70e1b6/bases/strictest.json
