Cloudflare Zero Trust for Service Token

Hi there, I’m using WARP and Zero Trust to connect to my Zero Trust VPN, I’m using Linux ubuntu as client, This is the pattern of my mdm.xml:

  <string>[client secret]</string>

When I remove the file and try using warp-cli teams-enroll [team_name] everything works fine, however if I try passing the mdm.xml file, this is what I got:

warp-cli register
warp-cli connect
warp-cli account
Error: Missing registration. Try running: warp-cli register

In my dashboard shows as if the service token has never been used.

I already enabled on Device enrollment permissions to allow any non-expired service tokens.

Any Ideas.
