类型“false”没有调用签名。(tsserver 2349)

我收到以下内容的Typescript警告:

let d: { [key: string]: { [k: string]: boolean } | number[] } = {
  blah: [],
};
d["blah"].push(2);

警告:

 This expression is not callable.                                               
 Not all constituents of type 'boolean | ((...items: number[]) => number)'    
 are callable.                                                                  
 Type 'false' has no call signatures. (tsserver 2349)  

代码有效,如果我控制台.log(d['blah']),我得到 [2] 。为什么我收到警告?如何更正(或忽略)?

我的tsconfig:

{
  "compilerOptions": {
    "target": "es2015",
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,
    "skipLibCheck": true,
    "strict": true,
    "noEmit": true,
    "esModuleInterop": true,
    "module": "esnext",
    "moduleResolution": "bundler",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "jsx": "preserve",
    "incremental": true,
    "plugins": [
      {
        "name": "next"
      }
    ],
    "paths": {
      "@/*": ["./*"]
    }
  },
  "include": ["next-env.d.ts", "**/*.ts", "**/*.tsx", ".next/types/**/*.ts"],
  "exclude": ["node_modules"]
}

我试着打印到控制台,代码有效,所以我很困惑为什么警告有效
