No log store configured through the application property '%s

Error message

No log store configured through the application property '%s' (nor a fallback '%s'). Supported types are: %s

What it means

Thrown by KestraBeansFactory when no log data-store backend is configured. It reads kestra.logs.type, falling back to kestra.repository.type; if both are null it cannot construct a LogDataStoreInterface and throws KestraRuntimeException listing the config property names and the supported type ids. This is a bootstrap/configuration error that prevents application startup.

Solutions

1. Set kestra.repository.type to a supported value (e.g. h2, postgres, mysql, elasticsearch) in application.yml.
2. Or set kestra.logs.type explicitly to decouple logs from the main repository.
3. Use the 'memory' alias for local H2/testing (it maps to the h2 backend).
4. Cross-check the value against getLoggableTypeIds() in the exception message to avoid typos.

Example fix

# before (no storage type)
# kestra:
#   repository:
#     type:
# after
kestra:
  repository:
    type: postgres

String type = logsConfig.type().orElse(repositoryConfiguration.type());
if (type == null) {
  throw new IllegalStateException('Configure kestra.repository.type or kestra.logs.type before startup');
}

When it happens

Trigger: getLogDataStorePluginId reads logsConfig.type() = empty and repositoryConfiguration.type() = null; the null branch throws KestraRuntimeException formatted with KESTRA_LOGS_TYPE_CONFIG, 'kestra.repository.type', and the factory's getLoggableTypeIds().

Common situations: Fresh install with incomplete application.yml (no repository type set), a config migration that removed kestra.repository.type without adding kestra.logs.type, env-var override blanking the value, or a profile that omits storage config.
