Flowable Database Exception

Flowable Engine
1

I am getting this error when I run my program:

org.flowable.engine.common.api.FlowableException: Could not update Flowable database schema: unknown version from database: ‘6.1.2.0’

The version of my db in act_ge_property is 6.1.2.0 and the flowable - engine dependency in my pom.xml file is 6.1.0

I read in one of the blogs that these 2 versions should match.

I’ve now downloaded Flowable 6.1.2 and added it in my pom.xml dependency.

But I still get the same error.

Thanks,

If you drop a later version of a jar into your project, it will upgrade the database to the latest version and you cannot go back to a previous version.

But it’s odd you get that too when using the 6.1.2. Can you put the exact contents of the act_ge_property table here?

Hi Joram,

I had both the 6.1.0 and 6.1.2 jars in my build path . I removed the 6.1.0 jars and it works fine now.:slight_smile:

Thanks,

I am getting this error when I run my program,But all applications version is ‘6.3.1’.And when I change the database to oracle,it works well. Below is error log:
Caused by: org.flowable.common.engine.api.FlowableException: Could not update Flowable database schema: unknown version from database: ‘6.4.0.0’

@guaiguaihuas Joram said you must have used 6.4.0 locally and you can’t go back to 6.3.1. If you have tried running the provided WARs then a database located under ~/flowable-db is used.

Thank you very much!I’ve aware of that.

This issues is caused due to DB version, just delete the flowable-db from your local and then deploy the war again.
