UIB error Event mapping target action is undefined

[Aman18]

Hi,

I have built a custom page and added Calendar component. Also added a custom modal to open the event record when clicked. Using Client state parameter to pass on the parameter from event id to the form controller using event clicket action. It is working as expected in lower instance.

But after migrating the code to higher instance modal is not opening and getting below error:

"getActionHandlers.js:348 Event mapping target action is undefined"

I have pushed the code multiple times capturing all the components again to be sure not missing any code. but still not working. Any idea why it's not working?

Thanks,

Aman

hi @Aman18 ,

Here's a summary of potential steps to troubleshoot your issue:

Check for Missing Dependencies: Ensure all related scripts and components are migrated correctly.

Verify Client State Parameters: Confirm they are correctly set and passed.

Check for Script Errors: Look for additional errors in the browser console.

Review ACLs and Permissions: Ensure proper access controls and permissions.

Compare Configurations: Identify any discrepancies between the lower and higher instances.

Clear Cache and Rebuild Scripts: Resolve issues from cached old data or scripts.

Debug with Logging: Trace execution flow to identify failure points.

Review getActionHandlers.js: Understand the cause of the "undefined" error.

Check Event Handlers: Ensure correct definition and mapping of event handlers.

Instance-Specific Issues: Consider involving ServiceNow support if needed.

Thanks,

Hope this helps.
