Changes:
- Switch namespace create payload from
channelNamespacetoid. - Handle
nullvalues forbatchingIntervalandconflationIntervalin create/update/delete command output. - Update integration test namespace creation payload to use
id.

Now that the CLI explicitly handles batchingInterval/conflationInterval potentially being null, the Namespace model (and related method return types) should reflect that (number | null) rather than only number. Keeping the type accurate will prevent future code from accidentally calling number methods on null and removes the need for non-strict null checks in consumers.

@coderabbitai do you think aboe suggestion is correct? Provide detailed explaination for the same
There was a problem hiding this comment.
@sacOO7, yes, Copilot's suggestion is correct. Here's a detailed explanation:
Current Type Definition
The Namespace interface currently defines these fields as:
batchingInterval?: number;
conflationInterval?: number;The ? operator makes these optional properties, which means their type is number | undefined. A property is undefined when it's absent/not set.
The Problem
According to the PR objectives, the API can explicitly return null for these fields (not just omit them). However, null is not the same as undefined in TypeScript:
undefined= property is absent/not setnull= property is explicitly set to null
Since the current types are number | undefined, TypeScript won't catch type errors if code assumes these are always numbers when the property exists:
// This would compile fine with current types, but crash at runtime if value is null
const interval = namespace.batchingInterval; // Type: number | undefined
if (interval !== undefined) {
console.log(interval.toFixed(2)); // ❌ Runtime error if interval is null
}The Fix
The checks in your PR were changed from !== undefined to != null (loose equality) specifically because the API returns null. The types should match this reality:
batchingInterval?: number | null;
conflationInterval?: number | null;This expands to number | null | undefined, which accurately represents:
- Field might be absent (
undefined) - Field might be explicitly null (
null) - Field might contain a number
Recommendation
Update the Namespace interface to reflect the actual API behavior:
export interface Namespace {
// ... other fields ...
batchingInterval?: number | null;
conflationInterval?: number | null;
// ... other fields ...
}This makes the type system more accurate and helps prevent runtime errors by forcing explicit null checks.

@coderabbitai https://github.com/coderabbitai It's also suggested to change channelNamespace into id, is it expected or no?
There was a problem hiding this comment.
@sacOO7, yes, changing channelNamespace to id is expected and correct. Here's why:
The Namespace Interface Uses id
Looking at the Namespace interface (which is the return type of createNamespace), the field is defined as:
export interface Namespace {
// ...
id: string; // ← The field name in the interface
// ...
}There is no channelNamespace field in the Namespace interface.
Input Should Match Output
The createNamespace method:
- Accepts parameters to create a namespace
- Returns a
Namespaceobject
The parameter field names should align with the field names in the returned Namespace type. Since the API returns an object with an id field (not channelNamespace), the input parameter should also use id.
Bug Fix Per PR Objectives
The PR description explicitly states:
"Previously failed because it sent
channelNamepsaceinstead ofidin the request."
This confirms it was a bug - the API expects id as the field name, but the code was incorrectly sending channelNamespace.
Summary
✅ The change is correct: The parameter should be id to match:
- The
Namespaceinterface field name - What the Control API expects
- Consistency between input parameters and output types
