Hi Prashanth,

It could be because you had 'Available for Input' ticked for that variable validationErrorMessage. You can find that checkbox when editing that variable in Flow Builder.

When you tick the box, that variable becomes a parameter to the flow. Since you probably weren't sending a value to it when invoking your flow, Salesforce tried to set it to null and failed there.

After you've updated your flow, remove the flow from your page, and readd it as well. 

Refer below thread with similar issue:
