When customizing flows, you can connect one subflow to another in a “nested” manner. However, the more subflows are nested, the greater the potential for recursion-related errors.
In v41.2 and later, we’ve limited the number of subflows that can be nested in a single flow to 100. If you are using an on-premise deployment of Hyperscience v42 or later, you can adjust this maximum by adding the HYPERFLOW_ENGINE_MAX_SUBFLOWS_DEPTH_LIMIT variable to your “.env” file:
HYPERFLOW_ENGINE_MAX_SUBFLPOWS_DEPTH_LIMIT=<maximum_number_of_subflows_nested_in_a_flow>We recommend increasing the value of this variable (e.g., HYPERFLOW_ENGINE_MAX_SUBFLOWS_DEPTH_LIMIT=120) only if your use case requires more than 100 nested subflows to be nested in a single flow.
If you are using a SaaS deployment of Hyperscience v41.2 or later and need to increase this limit, contact your Hyperscience representative.
