215 | } = change
216 | const sourceNode = nodes.find(node => node.id === edge.source)!

217 | nodesConnectedSourceOrTargetHandleIdsMap[sourceNode.id] = nodesConnectedSourceOrTargetHandleIdsMap[sourceNode.id] || {
| ^
218 | _connectedSourceHandleIds: [...(sourceNode?.data._connectedSourceHandleIds || [])],
219 | _connectedTargetHandleIds: [...(sourceNode?.data._connectedTargetHandleIds || [])],
220 | }
