Marek Šneberger: [go client]
Hello from Czech republic! 
Is there some documentation / explanation in which case to use NewThrowErrorCommand() or NewFailJobCommand() and what is the difference?
Thanks 
korthout: Hi @Marek Šneberger
They are both described in the gRPC reference: https://docs.camunda.io/docs/reference/grpc
Generally:
• use FailJob when a technical error occurred
• use ThrowError when a business error occurred
In Bpmn a business error can be modeled in the process using error events: https://docs.camunda.io/docs/reference/bpmn-workflows/error-events/error-events
Technical errors should be left out of the process definition and handled exceptionally (an incident is raised, stopping the execution of the process, after the problem has been resolved, the incident can be resolved)
