问题描述
我在电子邮件模板上有一个CTA按钮。当我单击它时，它应该重定向到登录页面并以pdf格式下载。
当我下载pdf时，除图像外，所有内容均已生成。
如果我使用常规图像，则无法正常工作，但是如果我使用data:image/png;base64,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，则可以正常工作。
将我的代码放在下面。如果我能得到任何帮助的话，那真是太好了。 谢谢
