When a filter has a single result, it returns as a record instead of an array (see Selecting conditional data | Postman Learning Center).
This means that when a list is filtered and the result happens to be a single record then it cannot be processed by a For block, which expects a list as input. How can this problem be solved so that a filtered list can be processed by a For block even if there might be only a single result?
See the example flow in my public workspace: Postman
Many thanks!
