Had same problem. Seems you have css validation fix. They fixed that at jestjs/jest#8005, you have to update jest version in your package.json, run npm install and update package-lock.json too, so travis would use new jest version. For example, i choosed to update to version 24.8.0, it helped to discover real errors

При создании Pull request указывал на ошибку в каком-то файле из предыдущих заданий. Я его удалил, ошибка ушла. Потом обновил Pull request также выдал ошибку из предыдущих заданий, после удаления этих файлов возникла эта ошибка.
