RESTResponseV2 async timeout

[Che Pazzo]

I am running an async execution of sn_ws.RESTMessageV2:

var request = new sn_ws.RESTMessageV2(name, method);
var response = request.executeAsync();
response.waitForResponse(60);

In this case, if the response takes longer than 60s, it throws a `com.glide.ecc.ECCResponseTimeoutException` error. This is *not* a standard javascript Error object (e.g. it uses `class` instead of `name`).

Is there any documentation anywhere about this? The best I can find is in the Scripting Outbound REST doc that reads: "Might throw exception timing out waiting for response in ECC queue.", which isn't very helpful.

A walk through the properties shows the following list, so I can piece together how to handle them, but if there is actual documentation out there, that would be better.

properties:

• getClass
• wait
• localizedMessage
• printStackTrace
• getLocalizedMessage
• notifyAll
• initCause
• getMessage
• cause
• message
• getCause
• notify
• addSuppressed
• setStackTrace
• getStackTrace
• hashCode
• equals
• toString
• getSuppressed
• stackTrace
• suppressed
• class
• fillInStackTrace

Ankur,

I'm not looking to control the timeouts, but rather to catch and handle the exception that is thrown.

Hi Mike,

Use try catch block as below

and check

try {

var request = new sn_ws.RESTMessageV2(name, method);  

var response = request.executeAsync();  

response.waitForResponse(60);

}

catch(ex) {

var message = ex.getMessage();

}

Ankur,

I know how to catch errors, but I'm looking for documentation on this error, specifically.

e.g. I can identify this error with:

if (ex.getClass() == 'class com.glide.ecc.ECCResponseTimeoutException') {
   do('deal with this, maybe try again');
}

The problem is that pretty much *every other* error uses `name`, while this one uses class. This is a problem when the error could just as easily have been a ReferenceError, for which `getClass()` would return `undefined`. In short, it's different from a normal Error object, so I would expect that it should be documented somewhere.

The REST V2 doc specifically mention that an exception might be thrown. I'm looking for the docs on this exception.

e.g. What does `getClause` do?

e.g. What other exceptions are there? is it just the ECC Timeout?

e.g. What is the meaning of `wait` in the context of an exception that has already been thrown?
