A scatter-gather router is configured with four routes:Route A, B, C and D.

The result of accessing route C failure is Error,errorMessage,payload.failures[‘2’]. This is because a scatter-gather router returns an aggregated message that contains an array of results from each route and an array of failures from each route. The failures array contains error objects with information about each failed route execution. To access route C failure, which is the third route (index 2), the developer needs to use Error.errorMessage.payload.failures[‘2’] expression.
