Heap Space Error when deploying BPMNs to

1

Getting the error below when deploying my BPMN files using a custom config with Spring Autdeploy… Is there any way to stop the engine from generating raster graphics on startup (ideally in the config)?

 Message: Error while generating process diagram, image will not be stored in repository

My guess is that processEngineConfiguration.setCreateDiagramOnDeploy(false) would do it but I’ve never actually used this setting.

Thanks so much, that seemed to work…
I wish I knew more about these flags, going to take a look through them and see what each one does to make sure I’m not turning on something I don’t need/will consume many resources.
