Making a home server and keeps saying (no license key specified

it just shows this code in the config file
GlobalError: This server does not have a license key specified. Please set the sv_licenseKey console variable to a key from https://keymaster.fivem.net/. (for example, set sv_licenseKey "key" in the config, or +set sv_licenseKey key on the command line)

This is my server.cfg

# you probably don't want to change these!
# only change them if you're using a server with multiple network interfaces
endpoint_add_tcp "0.0.0.0:30120"
endpoint_add_udp "0.0.0.0:30120"

start chat
start spawnmanager

sv_endpointprivacy true

# server slots limit (must be between 1 and 31)
sv_maxclients 30

# license key for server (https://keymaster.fivem.net)
sv_licenseKey "removed"
