Debugging client-side scripts in ServiceNow involves utilizing tools and methods that operate within the user's browser environment, as client-side scripts execute there.

A. gs.addErrorMessage(): This function is used in server-side scripts to add error messages to the session and is not applicable for client-side debugging.

B. g_form.addInfoMessage(): This client-side function displays informational messages to the user on the form. While primarily used for user communication, it can aid in debugging by confirming the execution of certain script sections.

C. jslog(): This function logs messages to the JavaScript log, which can be viewed using browser developer tools. It's a valuable tool for debugging client-side scripts by providing runtime information.

D. gs.log(): This function logs messages on the server side and is not available in client-side scripting.

Additionally, developers can use the debugger; statement within their client-side scripts. When the browser's developer tools are open, encountering this statement will pause script execution, allowing for step-by-step inspection.

Application Access is a feature that allows you to control the access level of other application scopes to your application’s data tables. By setting the Accessible from field value to This application scope only, you can restrict the access to your data tables to only your application scope. This means that other application scopes cannot create, read, write, or delete records on your data tables, unless they have explicit permissions through Access Controls or other means.

In ServiceNow, when configuring a REST Message, the Endpoint specifies the URI (Uniform Resource Identifier) where the REST request is sent. This URI points to the resource on the external system that the REST message will interact with, whether it's to retrieve, update, create, or delete data.

Key Points:

Endpoint Definition: The Endpoint is a complete URL that includes the protocol (e.g., HTTP or HTTPS), the domain or IP address of the external server, and the specific path to the resource. For example: https://api.example.com/v1/resources.

Dynamic Endpoints: ServiceNow allows the use of variables within the Endpoint URL, enabling dynamic substitution at runtime. This is useful when the exact resource path or parameters need to be determined during execution.

Configuration in ServiceNow:

Navigate to "System Web Services" > "Outbound" > "REST Message."

Create a new REST Message or select an existing one.

In the REST Message record, define the Endpoint URL in the "Endpoint" field.

Example Scenario:

If you are integrating ServiceNow with an external ticketing system to retrieve incident data, the Endpoint might be something like https://api.ticketingsystem.com/incidents/{incident_id}, where {incident_id} is a placeholder that gets replaced with the actual incident ID at runtime.

Business Rule is server-side, so it uses GlideSystem API. gs.hasRoleExactly doesn't exist

In a Business Rule, the following returns true if the currently logged in user has the admin role:

gs.hasRole(‘admin’). This is the correct answer because gs is the GlideSystem object, which provides methods for performing system operations, and hasRole is a method that checks if the current user has the specified role. For example, gs.hasRole(‘admin’) will return true if the current user has the admin role, and false otherwise.

The following do not return true if the currently logged in user has the admin role in a Business Rule:

g_form.hasRoleExactly(‘admin’). This is not correct because g_form is the GlideForm object, which provides methods for manipulating forms, and hasRoleExactly is a method that checks if the current user has exactly the specified role and no other roles. For example, g_form.hasRoleExactly(‘admin’) will return true if the current user has only the admin role, and false if the current user has the admin role and any other role.

g_form.hasRole(‘admin’). This is not correct because g_form is the GlideForm object, which provides methods for manipulating forms, and hasRole is a method that checks if the current user has the specified role or any role that contains the specified role. For example, g_form.hasRole(‘admin’) will return true if the current user has the admin role or any role that contains the admin role, such as admin_ui or admin_script.

gs.hasRoleExactly(‘admin’). This is not correct because gs is the GlideSystem object, which provides methods for performing system operations, and hasRoleExactly is not a valid method of the gs object. There is no method that checks if the current user has exactly the specified role and no other roles in the gs object. References: Business Rules, GlideSystem, GlideForm
