RESTHandler returns no errorMessages when requiredCriterion fails

SmartClient Version: SNAPSHOT_v13.1d_2024-10-06/AllModules Development Only (built 2024-10-06)
and
SmartClient Version: v13.0p_2024-10-05/AllModules Development Only (built 2024-10-05)


Hello, please try this test case here https://www-demos.smartclient.com/sm...uiredCriterion

modified as (for 13.1):

isc.RestDataSource.create({
    ID:"worldDS",
    dataURL:"https://www-demos.smartclient.com/smartclient-13.1/isomorphic/RESTHandler?dataSource=worldDS&operationType=fetch&operationId=fetchByRequiredCriterion"
}).fetchData()

or like this for 13.0:

isc.RestDataSource.create({
    ID:"worldDS",
    dataURL:"https://www-demos.smartclient.com/smartclient-13.0/isomorphic/RESTHandler?dataSource=worldDS&operationType=fetch&operationId=fetchByRequiredCriterion"
}).fetchData()

You'll see the correct error code 13 in the response, but no errorMessages.

Hello, actually I just realized that for this kind of error, the response protocol seems different, as in the requiredCriterion sample I think, where the response is:

{
    affectedRows:0,
    invalidateCache:false,
    isDSResponse:true,
    missingCriterion:"Area (kmē)",
    queueStatus:-1,
    status:-13,
    data:null
}

so maybe this is the actual problem?

Hello, please let me know if you see the issue or need any additional details.
From my perspective, it seems the RESTHandler should return a response similar to the one in post #2.

Sorry for the delay. This issue has now been fixed; the fix will be present in builds of 13.0 and greater as of tomorrow, December 20th.

Hello, sorry for the delayed feedback. I've tested this with both latest version 13.0 and 13.1, and it only works if I don't use the "Simplified REST" syntax.
Using the test case from the first post - modified to use the Simplified syntax (this is for the 13.0 showcase, requiredCriterion sample):

isc.RestDataSource.create({
    ID:"worldDS",
    dataFormat:"json",
    dataURL:"https://www-demos.smartclient.com/smartclient-13.0/isomorphic/RESTHandler/worldDS/fetch/fetchByRequiredCriterion"
}).fetchData()

I still get this response in the browser's Network tab:

<SCRIPT>//'"]]>>isc_JSONResponseStart>>{"errorCode":-13,"errorMessages":[]}//isc_JSONResponseEnd

(Note: in the RPC tab of the Developer Console, there's a "Transport Error" - is that expected?)
