Hi, I have a process which loops an array "n" no. of times.

Hi Phani, when you mention "fix the issue for the broken index in the loop and retry", if you are planning to edit the process model, restart the broken node? as per my understanding, yes then it will proceed from the next index.

Good practice would be to handle the error in the process/loop, so that the process does not break if an error is thrown. Additionally, depending on your requirement, you may need to validate the data being passed in to the process/loop before it starts to prevent errors occurring.

Hi Ryan,
How can we handle the error in the process/loop.
What error handling mechanisms are avialable.
Could you please give more inputs.

You can make use of Exceptions to handle the errors.

This will depend on what you are doing. For example, several smart services have an error code output; if the output value is populated you can take a different path in your process. If this doesn't help, you may need a rule that can validate the data, and then handle any errors in the data that are detected by the rule.
