Resolve VSCode Errors and Typescript 4.4+ Discrepancy

Question

Typescript 4.4 introduced the useUnknownInCatchVariables option that is enabled by default when tsconfig has strict enabled. This option changes the type of e in catch from any to unknown. Consider the following code:

// index.ts
function example() {
  try {
    throw new Error('Foo')
  } catch (e) {
    console.log(e.stack)
  }
}

example()

VSCode sees the above code as valid and looks like the following on highlight (note how it sees the e as type any):

There are no highlighted errors. However tsc generates:

index.ts:5:17 - error TS2571: Object is of type 'unknown'.
32     console.log(e.stack);

My tsconfig:

{
  "compilerOptions": {
    "target": "ES2015",
    "module": "commonjs",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true,
    "outDir": "build",
    "sourceMap": true
  },
  "include": ["index.ts"],
  "$schema": "https://json.schemastore.org/tsconfig",
  "display": "Recommended"
}

How do I resolve this inconsistency and utilize the new useUnknownInCatchVariables while seeing errors in VSCode?

After much messing around it ended up being simple. Didn't think about it before but updating VSCode to the latest version fixed the issue.
