# 11320: Invalid template unclosed brackets

Log Level: ERROR

## Description

This error occurs when your URL template is not formatted correctly. Check the template for unmatched variable brackets, especially in `media` or button `url` fields that use Content API variables.

### Possible causes

* A variable placeholder in a URL starts with `{{` but does not end with `}}`.
* A media URL or URL button was edited manually and left unmatched brackets in the template string.
* A sample URL path was added incorrectly when inserting variables into a URL-based field.

### Possible solutions

* Review each templated URL and make sure every opening `{{` has a matching closing `}}`.
* Use supported variable placeholders such as `{{1}}` or `{{IdName}}`. Do not include spaces inside variable names.
* If the URL uses variables in `media` or `url`, provide a valid sample value in the `variables` object so the combined URL resolves to a publicly accessible file or website.
* Save the corrected template in Console or resend the corrected Content API request.
