If the file output process does not start after the flow is executed, it is possible that the variable "recordId" or "ids" is not properly passed to the OFC flow component. Check that the values of the "recordId" and "ids" variables are set correctly before executing the OFC flow component.
How to check
1.Create a new temporary variable "tempRecordId" of text type.
2.Add a flow "Assignment" before the OFC flow component and assign the value of recordId to "tempRecordId", or in the case of "ids", assign it in the loop process.
3.Check the "Assignment" on the debug screen and confirm that the "recordId" is assigned to "tempRecordId".
If "recordId" is correctly assigned to "tempRecordId" but no output is generated, set "tempRecordId" to the record Id of the OFC flow component.
