Problem upgrading to host v4.28 for HTTP streaming functions in VSCode

[stevefsc777]

4.28+ "Worker was unable to load entry point "src/index.js": HTTP streaming requires Azure Functions Host v4.28 or higher."

JavaScript

In VSCode I created a HTTP function via the command palette. It used the v4 structure for functions - api/src/index.js, rather than the structure I'd used prevously - api/funcname/index.js

I'm getting this error, "Worker was unable to load entry point "src/index.js": HTTP streaming requires Azure Functions Host v4.28 or higher."

I've installed & reinstalled the various VSCode extensions for building static web apps and the SWA CLI but the function host version remains at 4.27.xx.xx. I've also gone through the proces with node 16.x, 18.x and 20.x.

I've searched extensively and although I've found several articles relating to this issue, mostly from 2023, I haven't found anything that has helped me solve the problem.

What am I missing?

Thanks for any help/suggestions. I've been trying all day to resolve this.

Hi @stevefsc777 - what version of core tools are you using (func --version)?

Host version 4.28+ is pretty old so I would expect you would be fine from the latest CLI version onwards. v4.5.0 for example brings in host versions:

• Host Runtime Version: 4.1044.400
• In-Proc Host Runtime Version: 4.44.100 (includes 4.844.100, 4.644.100)
