how to manage exceptions in SAP Data Intelligence?

[amish1980_95]

Hello Folks,

How should we handle the exceptions in SAP Data Intelligence?

I want to provide a custom error message and handle the exceptions in the graphs.

Thanks,

Indu Khurana.

Hi Indu,

can you please clarify which kind of scenario we are talking about? Do you want to create a custom script operator (Python, Node, Go) and handle exceptions in the script code?

[kai-michael_roesner]

There is no standard operator to catch and handle exceptions from anywhere in a graph. Generally, operators catch and handle exceptions within their code. These are then either logged or sent to an error output port. Sometimes you can also configure operators to terminate the graph on errors. For operators (including your own custom script operators) that have an error output port (of type message.error) your can collect their error outputs and connect them to a custom error handling operator which you would have to create for that purpose.

Best regards
Kai.

Hello Kai,

For the operators with message.error port, the graph dies and I am not able to capture the exception like I can do with error port 'outError'.

Can you advise on it?

Thanks,

Indu.

Hi Indu,

which version of SAP Data Intelligence are you using? Can you be a bit more specific about how exactly you tried to use the error ports?

Best regards
Kai.

Hello kai-michael.roesner,

Thank you for responding.

I'm looking for an exception management framework which could be used in general for the graphs and where we could provide custom error messages.

Do we have any standard operator to handle exceptions?

Or do we need to create a custom operator to achieve this, if yes then I would appreciate if you could provide insights on this.

Thank you,

Indu Khurana.

You mean a standard operator that would catch and handle exceptions from other operators in the graph? Where do you want to provide your custom error messages, in the logs or in a terminal UI? (And please answer in a comment, not in an answer... 🙂

Hello kai-michael.roesner,

Thanks for responding.

My apologies, I din't realise I wasn't commenting but adding to the answer.

Yes, a standard operator to catch and handle exceptions.

I want to provide custom message in terminal UI.
