I am working on an angular applications and build a web application (Rest API) on IRIS for health, the web application uses a password authentication and setup with the default csp session time out (15 minutes). If the user make an REST API call from the angular application after the session expired, it displays a login prompt...is that anyway that we can disable the login prompt and just simply return http status 401? When the angular application received the status 401, it can redirect to angular error page.

Hi All,
I am implementing REST API's in IRIS using the below link as a guide.
I chose this approach so i could have a single entry point for requests regardless of namespace


a sample form the HIHLib.REST.Server class i am using is below. my question is does IRIS and CSP cache responses for requests to the CSP.REST class?
and if so what parameters or properties do i need to enable?

ERROR #9406

I'm trying to send a POST request to my REST API and I'm getting this error and most likely due the lack of experience, I have no idea how to fix this issue:

"error": "ERROR #9406: Unexpected format for value of field, AlertText, using class base mapping",

"id": "JSONImportError",

"params": [


"class base"


Am I missing something from my string definition?

I'm currently re-engineering an application from CSP pages directly accessing COS Methods, to an Angular/Material front end accessing a REST DAL. Both the Angular front end and REST services are hosted from the same Caché instance and the same namespace, but the REST services have their own CSP application, with all calls being routed through a Dispatch class.

REST POST 405 error

I'm testing out the new %CSP.REST way of creating an api and having a problem with a POST getting a 405 error.

I get data returned when I do a GET, so I don't think it's a configuration issue or a class issue.

I have no problem with %CSP.Page when creating a REST type method. So what am I missing?

Can someone give me some advice?

Thank you.

We have a Cache database in Azure, and want to expose it as an OData source (link).

My first attempt was to use Microsoft's Visual Studio 2017 and Entity Framework to create the data models...but it seems as if EF and Cache don't work together. (I do have those instructions from 2013, but they don't work. (See other post. Best answer seems to be "migrate to IRIS 2019.1.")

Is there any other form of OData support?

Hi Guys,

I have a DB server (ser-app-db) where IRIS is installed as server.

I have a Web server (ser-app-w) where IRIS is installed as web server and configured as CSP gateway.

I followed the configuration guide and ser-app-w perfectly display the CSP and CLS pages.

But that's not working for my REST service, for exemple with the REST sample:

http://ser-app-db/REST/CRM/Get?ReqID=123(GET): work and show the request

I've added a REST service which worked fine on our test system but failed on the production environment because UnknownUser does not have %All set and I really don't want it set on production (in fact I've also switched it off on test).

Is there a way to allow a single REST service to have unauthorised access?

I was thinking adding a resource/role to UnknownUser specifically for that service but I've never touched on Users/Roles/Resources so I'm struggling to work out what needs adding where.

When using the REST API classes for building services on a spec-first approach, the implementation class methods are usually built this format:

ClassMethod <method-name>(body As %DynamicObject) As %Stream.Object

But sometimes it keeps building the endpoint implementation method like this:

ClassMethod <method-name>(body As %Stream.Object) As %DynamicObject

It has been a problem because the rest of my implementation rely on the fact that the "body" object is a DynamicObject.

login failure

I am still working on iris-for-money app: https://github.com/oliverwilms/iris-for-money

Account.csp posts a rest call with _SYSTEM username and the password.

xhttp.open("POST", "/restapi/sql/" + query, true,"_SYSTEM","SYS");

/restapi web application has Password Authentication Method enabled.

SYS is the correct password for _SYSTEM user.

I do not understand why I see login failure in Audit database.
