I have followed all the steps mentioned here Exercise-4 Durable function however I am facing error when I call the client function through URL (followed mentioned instructions for the same)

Please check below error I'm facing-

NOTE-function version is -4 (default)

2024-04-02T17:17:20.396 [Information] Executing 'Functions.HttpStart' (Reason='This function was programmatically called via the host APIs.', Id=2555996a-c529-4a13-8ad4-762910d2953b)

Detailed solution for above excercise to complete is I installed durable function @2.1.4 but problem didn't solve further I noticed in package.json there was no entry for durable function which orchestration client function take reference to so I modify package.json code.

{

"dependencies": {

"durable-functions": "2.1.4"

} } in command prompt ran npm install which installed node_modules. & then hit the url of httpstart function which returns the json below

Hi @Nikita Netajirao Pawar I ran into the same problem as you did. So replicated the learn lab using Create your first durable function in Azure using JavaScript | Microsoft Learn as a guide in VS Code. When I attempted to debug, I received Worker was unable to load function OrchFunction: 'df.orchestrator is not a function' error message stating that the OrchFunction was not a function, even though everything was created successfully. I downgraded the durable-functions package to 2.1.4 it successfully ran locally. After that, I went back to the console in the sandbox and ran npm install durable-fuctions@2.1.4 and reran the HttpStart function URL. Low and behold, it successfully ran. Since this is node we're dealing, it could be an issue between the 3.1.0 and Node 18. I'll share this feedback with the team but for now, I suggest using 2.1.4 or trying using a different version of Node.
