Hybris entity not found when running cron job-CodePudding

I try to call the method synchronizeFull of the class DefaultCatalogSynchronizationService from my code which should sync from a source catalog to target catalog.
When I use the backoffice everything works fine, but when I use my code everything goes wrong.
The cron job called by this class fails each time and I get the following error:

ERROR [hybrisHTTP2] (0000009D) [Job] Caught throwable Entity not found ( pk = 
8796096201204 name = 'de.hybris.platform.persistence.processing_Job' type code =

any idea?

UPDATE:
Here is the code which I call in one of my classes (the CatalogSynchronizationService is a standard class of hybris)

this.catalogSynchronizationService.synchronizeFully(source, target);

UPDATE 2:
The sync seems to work fine when I remove the value of a field called Exploded drawing (which contains a picture of the product) from the product.

CodePudding user response：

use local session context to run syncjob programmatically, as below.

return getSessionService().executeInLocalView(new SessionExecutionBody()
        {
            @Override
            public Object execute()
            {
                this.catalogSynchronizationService.synchronizeFully(source, target);
           return true;
            }
        });

Or use

synchronizeFullyInBackground(final CatalogVersionModel source, final CatalogVersionModel target)

CodePudding user response：

I solved the problem, so I'll post the answer in case someone in the future will need it:

final CatalogVersionSyncJobModel syncJobModel = (CatalogVersionSyncJobModel) catalogSynchronizationService .getSyncJob(source, target, code);    
catalogSynchronizationService.performSynchronization(Collections.singletonList(product), syncJobModel, getSyncConfig());
