What is the difference if we write propagate to and don’t write propagate to?

Question

Accepted Answer

Using propagate to determines whether an exception should be propagated to the caller or not.

If propagate to is not used, the exception will not be propagated to the caller and will be handled within the flow.
If propagate to is used, the exception will be propagated to the caller and can be handled by the calling flow or application.
Propagate to can be used in conjunction with exception handling nodes like Try-Catch or Throw.
Example: If a flow calls another flow and an exception occurs in the called flow, using propagate to will allow the exception to be propagated to the calling flow for handling.
Example: If a flow has a Try-Catch node and propagate to is not used, the exception will be caught and handled within the Try-Catch node.
