为什么将日志级别设置为debug就报错，在info下正常运行：

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: 123456
    url: jdbc:mysql://192.168.3.17/sell?characterEncoding=utf-8&useSSL=false
  jpa:
    show-sql: true

server:
  servlet:
    context-path: /sell

logging:
  pattern:
    console: "%d - %msg%n"
  file: /var/log/tomcat/sell.log
  level: debug
