And I have the next problem:

ENGINE-09005 Could not parse BPMN process. Errors: 
* One of the attributes 'class', 'delegateExpression', 'type', or 'expression' is mandatory on serviceTask. | resource diagram_1.bpmn | line 13 | column 68 [ deploy-error ]

Can youhelp me?

Hi @Aleksandr_Ermolaev,

You should decide what implementation for service task to go with. It can be Java code or external implementation to be used (external task).

Please have a look at below docs
https://docs.camunda.org/manual/7.16/reference/bpmn20/tasks/service-task/
