Angular Portal Error Type Error: Cannot read properties of undefined (reading ColumnName)

Did you check if the newly added columns are also in the schema end-point: /imx/entityschema
Look for: "ColumnName": "Something"

Replying on behalf of Sameer -

Yes the schema has been defined and provided in the interface

export interface IClientProperty {

    /** Returns the name of the property. */

    ColumnName?: string;

Could be that the database permission to view the column value is not in place?

If you want to check/test the database permission:
Create custom role-based permission group: CCC_StartObjectBrowser
Assign to following program functions:
- ApplictionStart_ObjectBrowser
- ObjectBrowser_SQLEditor

Assign this Permission group to an Appliction role and assign this to the identity in question.
Start de objectbrowser and login with the identity you just configured with the permissions.
I personally find this really handy for troubleshooting permissions

Turns out to be that "defaultEMailAddress" is written in the code with a lower-case "d", but the debugger shows it with an upper-case "D". Which was the root cause of the issue.

thank you for taking out time to respond the query

The column name was case sensitive. The error got resolved after we updated column name from Lower Case to Upper Case.
