WeChat official account returns error 41000 when sending template message

Question

I didn’t find what the error code 41000 means in the WeChat public account development documentation. {"errcode":-41000,"errmsg":"invalid openid rid: 627e0e5d-677f959b-360c98c4"}, this is the information returned by WeChat

Answer 1

It is obvious that openid must be wrong, it should be that openid has become invalid after unfollowing it

Answer 2
