Rest API Start Before Activity is not working

When I am using Start Before Activity

This error is thrown-

Cannot perform instruction: Start before activity ‘Submit to Manager’; Element ‘Submit to Manager’ does not exist in process ‘5baca43a-5a32-11ef-b926-000d3af072d2’: element is null

Please advise. This is within the same process instance.

Hi @deepti
It would be helpful if you could share more details about the issue, such as the BPMN file, steps to reproduce the problem, and any additional information you think might be relevant.
