Cannot find module ‘@azure/functions’ or its corresponding type declarations

Recently, I was working with a requirement where I was trying to create a typescript Azure Function using the Visual Studio Code IDE. After creating the typescript Azure Function, I got this error.

The Azure Function code was as follows.

import { AzureFunction, Context, HttpRequest } from "@azure/functions"

const httpTrigger: AzureFunction = async function (context: Context, req: HttpRequest): Promise<void> {
    context.log('HTTP trigger function processed a request.');
    const name = (req.query.name || (req.body && req.body.name));
    const responseMessage = name
        ? "Hello, " + name + ". This HTTP triggered function executed successfully."
        : "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.";

    context.res = {
        // status: 200, /* Defaults to 200 */
        body: responseMessage
    };

};

export default httpTrigger;

I got this error.

You can see the error message below

cannot find module '@azure/msal-browser' or its corresponding type declarations.

The complete error message was as below

Now, we will see how to fix the error.

Cannot Find Module ‘@azure/functions’ or its Corresponding Type Declarations. [Solved]

To fix this, I have downgraded the Azure Functions Core Tools version from Version V3 to Version V2.

I have run the below npm command to install the Azure Functions Core Tools in the Visual Studio Code terminal.

npm i -g azure-functions-core-tools@2 --unsafe-perm true

Once I have installed this, you can see that the error is gone, and I can run the typescript Azure Function successfully without any issues.

Here is the output

cannot find module '@azure/msal-angular' or its corresponding type declarations.

This is how you can fix the error Cannot Find Module ‘@azure/functions’ or its Corresponding Type Declarations.
