"Invalid Action" Error When Accessing CSP

Question

Question

PRAVIN T · Dec 4

I’m facing an issue with a CSP-based web application.
The default.csp page loads correctly on both servers. However, when I try to open or submit the login.csp page on one server, it shows the error:

"INVALID ACTION"

The exact same codebase is deployed on another IRIS server, and it works there without any issues.

Summary of the issue:

default.csp → Loads successfully
login.csp → Fails with “INVALID ACTION” only on one server
No code changes between the two servers

Has anyone encountered this kind of scenario?
What configuration differences should I check between the two servers that might cause this behavior?

Product version: IRIS 2021.1

Are you using the IRIS login page or a custom login page defined in the Web Application?

A guess from the hip:

import of *.CSP is followed by compiling it to *.CLS, which is compiled to *.INT
import of *.CLS doesn't necessarily trigger a compile

Thanks for your support Robert.

But my issue is, I have an backup file when i restored it
server 1:
default.csp -> login.csp page are open
server 2:
default.csp -> login.csp (shows invalid action and its not point out the file)

Since you are using a custom login class maybe the warning at https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls... is relevant:

Usually, the login page is loaded before the user has logged in to InterSystems IRIS, so the requesting process runs under the CSPSystem user (or whatever user connects the CSP Gateway to InterSystems IRIS). As a result, the CSPSystem user must have sufficient privileges to load and run the code in the login page, which generally requires READ permissions on the resource protecting the database in which the login page is located.

Page not found, or Invalid Action? If it's page not found, how is the web application configured?

Make sure the CSPSystem user has read access to the database where your custom login page is located.

Hi guys,
Thanks for you support. I solved the isses and the issues is management portal misconfigurations.
When I disable "PRVIENT LOGIN CSRF ATTACK" then it will work as expected.
