#Error Handling

Error handling refers to the response and recovery procedures from error conditions present in a software application. It is the process comprised of anticipation, detection and resolution of application errors, programming errors or communication errors.

The Good Old Days

The %Library.DynamicObject class has been in IRIS since before it became IRIS. If you have been using it since the Cache days, you may want to brush up on some of its changes.

In Cache 2018, the %Get method only had one argument. It was the key to retrieving from the JSON, meaning that if your JSON object called myObj, it would look like the following:

Hello everybody,

In the documentation I read the following:

Alerts are messages generated by production components. InterSystems IRIS automatically writes the alerts to a log file and sends then to the production component named Ens.Alert. If your production does not have a component named Ens.Alert, then InterSystems IRIS writes alerts to the log file but does not send them to any component. The component named Ens.Alert can be of any class. The most frequently used classes for Ens.Alert are:

In the context of IKO (Iris Kubernetes Operator) the question of Service not redirecting dynamically to the correct Pod is still pending.
In production this can be dangerous since an overload (or any other simpler problem) can cause you to change the main Pod and leave the application inoperable until we intervene.

Intersystems support warned that this is still an issue of IKO, but there are some possibilities that I am studying.

To explore an idea I had, I would like the help of this Forum to answer the following question:

Hi,

While HL7 Errors ACKs come back in the soap response, the HL7v2 Error ACK message is not processed.

I used the SOAP Wizard to construct my classes, but the generated code doesn't handle the HL7v2 ACK.
Does health Connect have a class that handles this?

Failing an official solution should I go ahead and make make my own classes based on EnsLib.HL7.Operation.TCPOperation, but wrapping it with the generated SOAP handling code.

How have others dealt with this?

How can I prevent large number truncation when using the DynamicObject and DynamicArray classes to create JSON in objectscript and then parsing the result in javascript. Are there any global settings that configure the output when using these classes?

I am looking at converting to the new DynamicObject and DynamicArray classes to build JSON. Our current (homegrown) JSON library forces string representation of numbers too long because of errors we were seeing with long numbers being truncated on the client, I am hoping to accomplish the same with the new classes.

I have some code in a mac routine that use indentation and the "." character : 

 IF condition1 DO
     .WRITE YCR,...
     .WRITE YCR,...
     .WRITE YCR,...

I would like to add a try / catch block between the write statements.
I can't refactor the whole code and use indentation with curly braces instead (there is too much code, not written by me)

I have tried the following but it does not work (it compiles, but code stop running right before the try keyword)

The intersystems documentation gives the same description for both <MAXSTRING> and <NETWORK DATA UPDATE FAILED - MAXSTRING>. I suspect that the description for <MAXSTRING> is correct and the description for <NETWORK DATA UPDATE FAILED - MAXSTRING> was an accident. I would like to know what situation triggers the <NETWORK DATA UPDATE FAILED - MAXSTRING> error.

Hi all,

I have a rule to throw a message when there is an error. I want to prevent send the email if the origin of the error is the API to send the email

This is my rule

Now, If there is any error in any process, it works, but if there is an error in MyProduct.BO.SendEmail it is trying to send the error again, and it is a infinite loop.

Is there any way to check what is the origin and don't process if the origin is MyProduct.BO.SendEmail?

In a Business Process (BPL) I noticed that if I 'm using a "scope" to handle errors then inside the "scope" when a "call" is used, the "request" and "response" action (i.e set for callrequest.prop = request.prop & response.prop = callrespones.prop does NOT work !
The result is that the values of those properties in the callrequest are nulls (I do see the properties names in the content of the callrequest message)

Hello Community,.

I've updated the IRIS community form 2023.2 to 2023.3 and I didn't see the User defined(Sample) error messages in ^IRIS.Msg global even I verified in both pointer and data level. I re run the set x=##class(%MessageDictionary).Import("error.xml") After import I could see the pointers and data in ^IRIS.Msg

Is the User defined error will reset from the server after IRIS upgrade?

We have a data transformation where source is object collection (populated from a json file) and target is EnsLib.EDI.XML.Document.

If source file is large enough, transformation fails and we get <store> error and I quickly found this:

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=EBPLR_DTL_foreach which at the bottom in "Avoiding <STORE> Errors with Large Messages" section tells to:

RESTful Exception Handling

A beginner’s guide to Exception Handling in RESTful web services. The article gives an example how the various error conditions during processing a service request can be handled.

We expect our client – server communication working in a flawless operational condition, running error free software. But we are prepared to handle exceptions. Are we? So far in the examples of the previous sessions were not. We did not care about exceptions. The result? In any error incident it took ages to figure out what the problem is and more importantly how to fix it.

Hi Community,

I have created a HL7 production in my working environment, Ens.Alert ,EMailAlert, PagerAlert, and BadMessageHandler are created.

Can anyone explain how Ens.Alert and BadMessageHandler will work when an HL7 message in Passed in Business service and how these 2 are related when any error occurs in the Production envinorment?
