Add-in error

[raffaeler]

I followed step-by-step the instructions at https://github.com/sbroenne/office-coding-agent/blob/main/GETTING_STARTED.md

• Office 2021 desktop
• Windows 11
• Node version v24.14.0

I get the following error when running Word (from the command line as for the guide):

The only glitch I could see:

• when I run npm run register:win it installs the self-signed certificates for 127.0.0.1 successfully
• when I then run npm run dev, it requires to DELETE the certificate 127.0.0.1 twice and then install the Developer CA for Microsoft Office Add-ins

Suggestions?

Thanks!
