TypeScript
Spread types may only be created from object types
Spread types may only be created from object types.
TypeScript rejected an object spread because one of the spread operands is not known to be an object type.
Error AtlasError Documentation and ResolutionObserved message
Spread types may only be created from object types.
Why it happens
- A spread expression includes null, undefined, or a primitive value.
- A union type includes non-object members that have not been narrowed out.
- A helper returns a value whose type is too broad for safe object spreading.
How to fix it
- Only spread values that are known object types.
- Narrow union values before spreading them into a new object.
- Provide a safe fallback object when the source may be missing.
