I am not able to start Spring Boot server due to this error.

Actually I want to stop table creation operation in server startup . So I have written

  jpa:
    hibernate:
      ddl-auto: none

Also enabled following

spring:
  liquibase:
    enabled: false

Do I need to configure anything else .

It is solved by using following property in application.yml

flowable:
  databaseSchemaUpdate: none
