Guide / Every rule

Two identical flows between the same elements

The check bpmnlint/no-duplicate-sequence-flows, in the group Modelling rules.

Error

Why it matters

Two flows from the same source to the same target either do the same twice or say nothing the first one did not.

How to fix it

Delete the duplicate flow.

Where you see it

The editor puts a marker on the element while you draw, and the Problems tab of the sidebar lists it under Rules, with the rule name bpmnlint/no-duplicate-sequence-flows. In a terminal, penstock check --only rules reports it.

To change how strict this rule is, set no-duplicate-sequence-flows to error, warn or off in your .bpmnlintrc. See Validation.
