🐛Unable to install/activate cloudflared service on Windows Server 2025

[alexbrothman]

Describe the bug
I'm seeing the following error message when I I attempt to install/activate the cloudflared service on Windows Server 2025. The application successfully installs, yet running cloudflared.exe service install #### produces:

2024-12-06T00:19:57Z INF Installing cloudflared Windows service
2024-12-06T00: 19:57Z ERR Unable to determine extra arguments for windows service error="Provided tunnel token
is not valid (unexpected end of JSON input)." windowsServiceName=Cloudflared
Unable to determine extra arguments for windows service: Provided tunnel token is not valid (unexpected end of
JSON

I've tried using several different tokens and all produce the same error.

To Reproduce
Steps to reproduce the behavior:

1. Install the cloudflared 64-bit connector on Windows Server 2025
2. Run cloudflared.exe service install ####
3. See error:
   2024-12-06T00:19:57Z INF Installing cloudflared Windows service
   2024-12-06T00: 19:57Z ERR Unable to determine extra arguments for windows service error="Provided tunnel token
   is not valid (unexpected end of JSON input)." windowsServiceName=Cloudflared
   Unable to determine extra arguments for windows service: Provided tunnel token is not valid (unexpected end of
   JSON

Expected behavior
The service should activate and the endpoint should join the Tunnel.
