SR Policy: source address is not specified

I am using several Cisco ISR 4351s to do sr policy experiments. Six routers are configured with the basic configuration of MPLS VPN, so far no problems have occurred. When I started to deploy the sr policy, some error messages appeared. How can I solve this error? I did not find how to specify the source.

(Sorry for my poor English)

底下小伙伴提醒才发现这是中文社区,重新描述下情况,

6台cisco 4351搭建MPLS网络(另外有两台思科普通路由器当CE),用segment代替LDP标签,实验到这里没有问题。然后希望用sr policy进行选路,按照ios-xr的资料配置(4351是ios-xe),命令可能有稍许不同,但看起来该有的元素都配上去了,policy就是起不来,提示和配置在上面贴了,ios版本也贴了,求大佬指点一下。
