Strange error of vertical output on mysql 8

Question

Mysql 8 on Debian, with Galera 4.

mysql> select capabilities,view_seqno  from wsrep_cluster;
+--------------+------------+
| capabilities | view_seqno |
+--------------+------------+
|       184703 |        277 |
+--------------+------------+
1 row in set (0.00 sec)

Works fine, but when I want the vertical output...

mysql> select capabilities,view_seqno  from wsrep_cluster \G;

*************************** 1. row ***************************
capabilities: 184703
  view_seqno: 277
1 row in set (0.00 sec)

ERROR: 
No query specified

mysql> 

Why the error "no query specified" appear?

Answer 1

select capabilities,view_seqno  from wsrep_cluster \G;

You have executed two queries. The first ends with the \G. The second ends with the semicolon. The contents of the second query are the empty string.
