Error while developing extensions

Hello, 

I'm creating a custom extension but I'm getting this error.

Below the screenshot from the app an the Chrome console.

Here my configuration:

• Node v16.18.1
• @dashler78/blocks-cli@@2.0.3
• Template = https://github.com/Airtable/apps-hello-world-typescript

I've run this in different computers, Windows and macOS.
