TypeScript warns that the object is possibly undefined
error TS2532: Object is possibly 'undefined'.
TypeScript found code that uses a value as a defined object even though the type system still allows that value to be undefined.
Error AtlasError Documentation and ResolutionObserved message
error TS2532: Object is possibly 'undefined'.
Why it happens
- The value comes from an optional property, lookup, or function result that may be undefined.
- Control flow has not narrowed the value to a defined state before use.
- A refactor introduced an optional path without updating downstream consumers.
How to fix it
- Add a defined check before using the value.
- Refactor the code so the value is initialized earlier or required by the type.
- Use optional chaining or a fallback only if the undefined case is intended.
