Issue  

On logging in, the Constellation work portal fails to display the landing page and becomes unresponsive. The following errors are observed:  

On-screen error: 

ViewContainer 

Failed to display content. Contact the application administrator. 

Browser console error: 

Error while Rendering the component undefined: TypeError: Cannot destructure property 'routeKey' of 'this.appRoutes[n]' as it is undefined. 

Root cause  

The 'D_pzBuiltOnAppRoutingTable' data page, which resolves and combines routing table entries, returns stale, cached data. As a result, when the Constellation portal attempts to load, it receives an outdated routing table that lacks the required route for the landing page. This leads to the application attempting to access a non-existent 'routeKey' property, causing the 'Cannot destructure property routeKey' error.  

Solution  

Update to Pega Platform 24.2.2, see Pega Platform 24.2.2 patch resolved issues. 

                                                       OR

Workaround 

As a workaround, apply the following hotfixes: 

• HFix-C1743 on Pega Platform 24.1.2 

• HFix-C2254 on Pega Platform 24.1.3 

• HFix-C1833 on Pega Platform 24.2.0 

• HFix-C1184 on Pega Platform 24.2.1 

The hotfix alone might not fix the issue if the routing table does not contain a valid route. In such scenarios, follow the below steps in sequence until the issue no longer persists: 

1. Save the application rule.

2. Clear the browser cache and storage. 

3. Regenerate the application routing table 

• Navigate to the 'Advanced' section of the application rule. 

• Click the 'Generate routing table' button. 

• Unlock a ruleset; otherwise, the button will remain disabled.
