Issue
Title and steps come from the upstream issue and pull request.
Description
There has been an error processing your request Error message is getting displayed on UI
Steps to reproduce
1. Add any dropdown attribute to advanced search (Admin: Stores -> Attributes -> Product - > Add New Attribute /Choose existing attribute ex: color
Input Type should be: Dropdown
Storefront Properties: Use in Search: Yes, Visible in Advanced Search: Yes)
2. Front-end - Go to
Issue: "There has been an error processing your request" Error message is getting displayed
Note: There is no issue with Text Attribute. URL is working for Text attribute. Issue is observed for dropdown attribute.
This seems to be reported in #25438 but said to be fixed and closed, so I open up another one.
