We are migrating from v3 to v4 currently and have reached a critical problem. It seems like the routing does not work with numbers/int.

I took the basic example for Docs: https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-http-webhook-trigger?tabs=python-v2%2Cisolated-process%2Cnodejs-v4%2Cfunctionsv2&pivots=programming-language-typescript#customize-the-http-endpoint

We can see that the category is resolving perfectly fine, but the id is undefined.

import { app, HttpRequest, HttpResponseInit, InvocationContext } from '@azure/functions';

export async function httpTrigger1(request: HttpRequest, context: InvocationContext): Promise<HttpResponseInit> {
  console.log(request.params); // { category: 'books' }
  const category = request.params.category; // books
  const id = request.params.id; // undefined

  return { body: `Category: ${category}, ID: ${id}` }; // Category: books, ID: undefined
}

app.http('httpTrigger1', {
    methods: ['GET'],
    authLevel: 'anonymous',
    route: 'products/{category:alpha}/{id:int?}',
    handler: httpTrigger1,
});

No matter if I remove the route constraint it still is undefined.

Hi @e-karlsson, this appears to be working for me:

Can you confirm which version of the @azure/functions npm package you're on?

Hi @ejizba ! Thank you for taking the time. Very interesting. Here is the version I have in the package.json file:
"@azure/functions": "^4.0.0".

Also, I am running on Mac if that can make any difference here.

Yeah I'm on a mac as well. If you check your package-lock.json file, it should display the specific version of the npm package being used. For example:

"node_modules/@azure/functions": {
"version": "4.5.0",

Could you send screenshots of what you're doing? It might allow me to catch a difference.

Hm, that's odd.. Yeah sure, see below:

What do you mean with screenshots of what I am doing? I posted the example code above:

Any additional files that are of interest? My colleagues meets the same problem.

npm and node version:

➜  test-folder git:(main) ✗ npm -v
10.8.1
➜  test-folder git:(main) ✗ node --version
v20.15.0

Yeah two more things:

  • A screenshot of sending the request - are you using curl? The browser? Postman? etc.
  • The full logs from func start (above you just had the version info)

Hi.

See full logs below. Generated by first func start --verbose and then trigger a call with Postman. Tried through browser also, same result. The code that is executed is the one on top. No other functions. The project was generated by Visual Studio Code extension for Azure Function app, and the code taken from MS documentation.

➜  test-folder git:(main) ✗ func start --verbose
SkipInProcessHost compilation symbol is not defined.

Just to clarify the problem, I did a request also with endpoint http://localhost:7071/api/products/books/05, then it works as it see 05 as a string..

Okay, I figured out our difference! Projects created recently will have a new http stream feature enabled by default (more info here), but older projects (like I was testing on) will not. I can repro the issue with http streaming turned on and will look into a fix. Thanks for reporting!

In the meantime, you can workaround this by turning http streaming off. In your src/index.ts file you can either change enableHttpStream to false or remove the call to app.setup altogether

Hi @ejizba ! I have confirmed another issue with enableHttpStream enabled. When this setting is set to true and then deployed to Azure Functions, the calls are not being redirected internally in the app correctly. Hence, the requests timeouts. The problem was raised with MS support but I found the solution after your suggestion here.
