Suggested Fixes
- Ensure the URL expression uses valid runtime expression syntax if using pointers (for example {$request.body#/callbackUrl}).
- Verify that any property referenced in the expression exists in the request schema.
- Confirm that referenced properties are of string type to contain valid URL values.
- Absolute URLs should include protocol (http/https) and valid domain.
- Relative URLs should be properly formatted relative paths.
- Check for typos in property paths and expression syntax.
