Installing a custom teams app/bot receive error: Invalid value(s) specified for validDomains[0]

Question

I created a new app using the Visual Studio Code Microsoft Teams Toolkit.

The configuration was pretty straight forward, however, I ran into a problem when I attempted to install the base app into Microsoft Teams.

I had the following in my Development.env file, but had replaced the {BOT_ID} with the real id:

appname=myfirstbot
fullappname=myfirstbot
version=1.0.0
botId0={BOT_ID}
baseUrl0=https://localhost:3000

Unfortunately this caused an error when uploading the package to Microsoft Teams.

invalid value(s) specified for validDomains[0]
