Date picker is not working on catalog forms or its broken

[Atik]

Hi All,

There is a issue which we are facing now days on portal is Date picker on Date/Time type fields is not showing the calendar once we try to select the Date/Time on service Portal we have to refresh the page once then its allowing.

When we raise the case to ServiceNow support they declined to support that there is customization and that's the reason one of the function is coming as not defined, as I am new to Service portal, actively learning. Wanted know How I can troubleshoot this issue, Looking for the steps, It will be great if someone can help me with the possible solutions as well.

Thanks In advance!

Thats is exactly the problem SN pointed out.

Check the console and locate the script causing the issue, it could be a catalog client script or Script include.

If the issue is just if undefined function, i believe putting your code in try - catch block will fix the issue.

since it is a customisation, predicting exact solution will not be possible.
