TS2571 — Object Is of Type Unknown

Wat veroorzaakt deze fout

The unknown type is the type-safe counterpart of any. Unlike any, you cannot perform operations on unknown values without first checking their type. Catch clause variables in TypeScript 4.4+ default to unknown.

Hoe op te lossen

Narrow the type using typeof, instanceof, or a custom type guard. Use type assertions (as Type) if you are certain of the type. Check for specific error types in catch blocks.

catch (e) { console.log(e.message); }
