Add '()' to all uncalled decorators

Production Risk

Build will fail; resolve before shipping.

What this means

A TypeScript diagnostic (TS95044): Add '()' to all uncalled decorators. This diagnostic is emitted by the TypeScript compiler when add '()' to all uncalled decorators.

Why it happens
  1. 1A decorator is applied incorrectly or to an unsupported target
  2. 2The 'experimentalDecorators' flag may need to be enabled
How to reproduce

TypeScript compiler reports TS95044 during type checking.

trigger — this will error
trigger — this will error
// Triggers TS95044
// Add '()' to all uncalled decorators

expected output

error TS95044: Add '()' to all uncalled decorators

Fix

Enable experimentalDecorators

WHEN Using legacy decorator syntax

Enable experimentalDecorators
// tsconfig.json
{
  "compilerOptions": {
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true
  }
}

Why this works

Decorators require the 'experimentalDecorators' flag; TypeScript 5.0+ also supports the TC39 Stage 3 decorator proposal without the flag.
