@romain :
The slapos master allows to report the error to the slave instance. https://lab.nexedi.com/nexedi/slapos.core/-/blob/master/master/bt5/slapos_json_rpc_api/PathTemplateItem/portal_callables/JSONRPCService_updateSoftwareInstanceErrorStateFromJSON.xml
But this functionnality is not implemented in libslap. https://lab.nexedi.com/nexedi/slapos.core/-/blob/master/slapos/slap/slap.py#L511 https://lab.nexedi.com/nexedi/slapos.core/-/blob/master/master/bt5/slapos_slap_tool/ToolComponentTemplateItem/portal_components/tool.erp5.SlapTool.py#L557
It should not be hard to add it. And it will allow you to generate ticket on the slave itself, instead of the main instance.
