Introduction
The infamous error message Property Id Does Not Exist on Type Never is a frustration that many developers have encountered while working with TypeScript. It can be difficult to decipher exactly what is causing the error and how to resolve it. In this article, we will explore some common causes of this error and provide tips for troubleshooting and resolving it.
What is 'Never'?
The first step in understanding this error message is to understand the concept of never in TypeScript. Never is a type in TypeScript that represents a value that will never occur. It indicates that a function will either throw an error or loop infinitely, and therefore it will never return a value.
Table Comparison: 'Never' vs 'Void'
| 'Never' | 'Void' |
|---|---|
| Represents a function that will never return a value | Represents a function that may or may not return a value |
| Commonly used as a return type for functions that always throw an error or loop infinitely | Commonly used as a return type for functions that do not return a value |
Causes of the Error
One common cause of the Property Id Does Not Exist on Type Never error is mixing up the types of variables or objects. For example, if you have an object with a property called id and you accidentally reference Id instead (with a capital I), TypeScript will not recognize the property and throw the error.
Another cause of this error is using never in the wrong context. As mentioned earlier, never represents a function that will never return a value. If you try to access a property on a never type, TypeScript will throw the error because it does not know what properties exist on a value that will never occur.
Troubleshooting Tips
If you are encountering this error message, there are several steps you can take to troubleshoot and resolve the issue:
- Double-check the spelling and capitalization of any variable or object properties you are referencing.
- Make sure you are using never in the correct context – it should only be used as a return type for functions that will never return a value.
- Try assigning the value of the property to a new variable and then accessing it – this can help TypeScript recognize the property.
- If all else fails, try explicitly casting the object type to a known type.
Opinion: Is TypeScript Worth It?
TypeScript has become increasingly popular among developers for its ability to provide static typing and catch errors before runtime. However, some developers argue that the strict typing requirements are too cumbersome and slow down development time.
In my opinion, TypeScript is definitely worth it. While it may take some extra time upfront to define types and catch errors, it ultimately saves time and effort in the long run by preventing hard-to-debug runtime errors. Additionally, the improved code organization and readability provided by TypeScript make it easier for developers to collaborate and maintain code over time.
Conclusion
The Property Id Does Not Exist on Type Never error can be frustrating to encounter, but with the right troubleshooting methods, it can be easily resolved. By understanding the concept of never and double-checking variable and object types, developers can avoid this error and write more robust code. And, in my opinion, the benefits of using TypeScript outweigh any potential downsides.

Property Id does not exist on type never is an error message that appears in TypeScript when you try to access a property that doesn't exist on an object. The never type is used to represent values that can never occur.
To fix this error, you need to make sure that the property you're trying to access actually exists on the object. You can do this by checking the type of the object and verifying that the property is included in the type definition.
You're getting this error because you're trying to access a property that doesn't exist on the object. This can happen when you misspell the property name, or when the property isn't included in the type definition for the object.
No, this error should not be ignored. It indicates a problem with your code that needs to be fixed. Ignoring the error could result in unexpected behavior or runtime errors.
Yes, this error is relatively common in TypeScript. It often occurs when you're working with complex data structures or when you're using third-party libraries that have incomplete type definitions.
