Azure function is not deployed from VS - No HTTP triggers found

Question

I created an Azure POST function that works wonderfully locally. When I deploy the whole thing using VS, I see 'No HTTP triggers found.' in the output. The function does not appear in my dashboard

@Benjamin Koubik Thanks for your reply. Lets take a step back and do this in the same way I did at my end from scratch. Hopefully that might help.

We will do it using a new function app project right from scratch. Follow the below steps one by one:

• Create a new empty folder and open this folder using VS code.
• Then open the New terminal in VS code and navigate to this folder.
• Run the func init command, as follows, to create a functions project in a folder named LocalFunctionProj:

func init LocalFunctionProj --model V4

You're then prompted to choose a worker runtime and a language - choose Node for the first and JavaScript for the second.

• Navigate into the project folder:

cd LocalFunctionProj

• Add a function to your project by using the following command:

func new

• Choose the template for "HTTP trigger". You can keep the default name (httpTrigger) or give it a new name (HttpExample).
• Replace the existing content with below in your local.settings.json.

{

  "IsEncrypted": false,

  "Values": {

    "AzureWebJobsStorage": "DefaultEndpointsProtocol=https;AccountName=aidocumentanalysing;AccountKey=8DOb+NvimZg1b9GOCi1IeUTT7ZSq8fAJkqEXbqx0GOtfhSoAl4LNVvkz3BDIhcsvKu81xurMUqku+AStPfVeLQ==;EndpointSuffix=core.windows.net",

    "FUNCTIONS_WORKER_RUNTIME": "node",

    "AzureWebJobsFeatureFlags": "EnableWorkerIndexing",

    "FORM_RECOGNIZER_API_KEY": "22651ab54aad4a289c6988b743fcd1e0",

    "FORM_RECOGNIZER_ENDPOINT": "https://eastus.api.cognitive.microsoft.com/",

    "FORM_RECOGNIZER_CUSTOM_MODEL_ID": "workingplan-last-test-for-today"

  }

}

• You can find the function you added in the src/functions directory.
• Open the JS file and Add the below code:

const { DocumentAnalysisClient, AzureKeyCredential } = require("@azure/ai-form-recognizer");
const { app } = require('@azure/functions');

app.http('httpTrigger', {
    methods: ['GET', 'POST'],
    authLevel: 'anonymous',
    handler: async (request, context) => {
        if (request.method === "GET") {
            return { body: "Hello, world!" };
        }

        const { url } = await request.json();

        const client = new DocumentAnalysisClient(
            process.env.FORM_RECOGNIZER_ENDPOINT,
            new AzureKeyCredential(process.env.FORM_RECOGNIZER_API_KEY)
        );
      
        const poller = await client.beginAnalyzeDocument(
            process.env.FORM_RECOGNIZER_CUSTOM_MODEL_ID,
            url,
            {
              onProgress: ({ status }) => {
                console.log(`status: ${status}`);
              },
            }
        );

        const {
            documents: [document],
        } = await poller.pollUntilDone();

        if (!document) {
            throw new Error("Expected at least one document in the result.");
        }
        return { body: JSON.stringify(document.fields) };
    }
});

• In your VS code terminal run the below commands one by one:
  • npm install @azure/ai-form-recognizer
    • npm install @azure/functions
• Run your function by starting the local Azure Functions runtime host from the LocalFunctionProj folder.

func start

• Test and confirm it works locally.
• Then you can deploy to your Azure Function using func cli as: func azure functionapp publish FUNC_NAME
• Then check if you see the http_trigger getting deployed. Also test from portal.
• You should be also able to send the GET verb to this function app and it should show HELLO WORLD message.
