TS2551

Property '{0}' does not exist on type '{1}'. Did you mean '{2}'?

A property that doesn't exist is accessed, and a similarly named one does. Usually a typo: use the suggested name.

What it means

This is TS2339 with a suggestion: the property doesn't exist on the type, but one with a close spelling does, and the message names it.

Example

index.ts
const user = { firstName: "Ada" };
export const n = user.firstname;
ts-r-check -p tsconfig.json --pretty false ts-r output
index.ts(2,23): error TS2551: Property 'firstname' does not exist on type '{ firstName: string; }'. Did you mean 'firstName'?

Recorded by node scripts/verify-examples.mjs with ts-r built from commit 6deaf01. The example uses the default tsconfig: strict, target: es2022, module: esnext, moduleResolution: bundler.

How to fix

  • Use the suggested property name if it's what you meant.
  • If the property should exist, add it to the type.
