${"base64":" ","img":{"width":1919,"height":443,"type":"png","mime":"image/png","wUnits":"px","hUnits":"px","length":47472,"url":"https://raw.githubusercontent.com/vtexdocs/help-center-content/refs/heads/main/docs/en/known-issues/Marketing%20&%20Merchandising/error-400-bad-request-when-accessing-filter-page-with-special-character-in-value_1.png"}}$

Simulation

To simulate the behavior:

Set a field value (product specification or SKU) with a special character (parentheses, for example) in any category;
In the catalog, select a product from the category and set it up with the specification value created in the first step. Save the product;
Wait for indexing;
Access the category directly from the web site;
On the side filter (SearchResult control), click the specification value (filter) configured with the special character;
Error 400: Bad Request! Scripts are not allowed!

Workaround

To work around the problem, avoid using special characters in the product specification and/or SKU values.
