Camunda 7.14 to 7.15 Update - Error

We just updated our camunda engine from 7.14 to 7.15 and now we get following error while starting a new process instance. See log:
catalina.2021-06-02.log (584.0 KB)

Anyone has an idea what the problem could be and how to solve?

Could you explain the steps you followed to upgrade the version?

  • Minor versions database scripts are executed before major version upgrade?
  • Maven dependencies are updated to latest versions and redeployed the process application post db scripts execution?

yes before major upgrading the verion we executed the db update scripts 7.14_to_7.15

maven dependecies are updated too…

redeployed the process application post db scripts execution

what do you mean with post db scripts ?

means after executing the db scripts whether process application has been restarted/redeployed.

yes, it has been restarted

Does the script executed successfully for the version upgrade? Did you execute the script manually?

yes the execution was successful, and I executed the script manually.
in ACT_GE_SCHEMA_LOG table I habe version 7.15.0

Okay. Could you confirm on the compatibility level of a database? Which version of MSSQL server are you using?

USE <database_name>;  
GO  
SELECT compatibility_level  
FROM sys.databases WHERE name = '<database_name>';  
GO

If the database compatibility level of a database is <=80, then try increasing it to 100 or 120 and try.

To set this configuration to db execute the below script:

ALTER DATABASE <database_name>  
SET COMPATIBILITY_LEVEL = 120;  
GO

compatibility_level = 130

using mssql 14.0.2037.2

is this existing or you’ve updated? is the issue resolved with this level?
