I am following the guide here: learn.microsoft.com/en-us/office/dev/add-ins/quickstarts/outlook-quickstart-yo

My environment:

• Node v22.19.0
• Windows 11
• Visual Studio Code

I have followed all the steps as outlined in the tutorial:

1. Installed the yeoman generator npm install -g yo generator-office
2. Created the add-in project yo office
3. These are the options that I selected:
4. Choose a project type – Office Add-in Task Pane project
5. Choose a script type – JavaScript
6. What do you want to name your add-in? – My Office Add-in
7. Which Office client application would you like to support? – Outlook
8. Which manifest would you like to use? – Add-in only manifest

However, when I run npm start to test the project. All I get from localhost:3000/taskpane.html is Cannot GET /taskpane.html.

Things that have already been done:

• Uninstall node and reinstall
• Reboot the PC
• Cleaned npm cache
• Started a new project

I am lost here. I have asked gemini and chatgpt to no avail. I have researched if anyone has the same issue and nothing. This has happened in two different PCs. Not sure what is the problem. Please help.
