🕗 Version & Regression Information

• This changed between versions 6.0.3 and 7.0.2
• This changed in commit or PR: unknown (likely the codefix hasn't been ported to the native language server)
• This is the behavior in every version I tried, and I reviewed the FAQ for entries about quick fixes and the TS 7 native language server (none found)
• Note: 6.0.3 was tested in the Playground, where "Add missing properties" is offered. The Playground has no TS 7 option, so TS 7.0.2 was tested in VS Code 1.140.0.

💻 Code

type T = { a: number; b: string }
const t: T = {}

🙁 Actual behavior

Error: Type '{}' is missing the following properties from type 'T': a, b
"No quick fixes available" when TypeScript 7 Language Server is enabled

🙂 Expected behavior

Error: Type '{}' is missing the following properties from type 'T': a, b
Quick Fix "Add missing properties" is offered. After applying:

type T = { a: number; b: string }
const t: T = {
a: 0,
b: ""
}
