The default timeout setting for the action that calls a child flow is 1 day. you need to change it to something like P7D to allow enough time for the child flow to run before the parent action times out.

Yes, P7D means seven days. The timeout controls how long the action will wait for the child flow to respond. It doesn't control how long the child flow runs. But if the timeout is too short then when the child flow finishes and tries to return a value the parent flow has stopped waiting for it.
