QUESTION

Camunda embedded with H2: Cockpit Login fails

Asked 2022-Mar-09 at 08:50

I'm currently wokring on a product with the following conditions:

  • Spring-Boot (2.6) with Camunda embedded (7.16)
  • Connection to Camunda configured to use H2 (2.1.210) embedded with the following is configured in application.yml:
app:
  datasource-camunda:
    jdbcUrl: jdbc:h2:./h2/test;MODE=LEGACY
camunda:
  bpm:
    database:
      schema-update: true
    auto-deployment-enabled: true

and as Java-Configuration:

@Bean("camundaBpmDataSource")
@ConfigurationProperties
public DataSource camundaDataSource() {
  return DataSourceBuilder.create().build();
}

@Bean
public PlatformTransactionManager camundaBpmTransactionManager(DataSource datasource) {
  return new DataSourceTransactionManager(datasource)
}

The camunda engine is not configured explicitly since I used the appropriate starter and let Spring auto configured it. As a result the resulting setup should look very similar to the embedded camunda h2 configuration showed here: https://docs.camunda.org/get-started/spring/embedded-process-engine/

The application runs good with this setup. No problems with the application at all, but I faced an issue while logging in to the camunda cockpit. Login succeeds but then I see an error in the login mask saying:

Login Failed

An exception occured in the persistence layer. Please check the server logs for a detailed message and the entire exception stack trace

Remove the "MODE=LEGACY" from the url. Here is a working example:

https://github.com/rob2universe/vanilla-camunda-template/blob/4625376bf3a5eed9cd1f2853cdf07fe5eca46685/src/main/resources/application.yaml#L17

Also ensure you use a supported H2 version. That is 1.4.x fro 7.16.x: https://docs.camunda.org/manual/7.16/introduction/supported-environments/

The BOM will inclcude H2 1.4.200.
