Preview Email Errors

[tony_le2]

Hi guys,

Whenever I preview any email templates from Marketing > Email Templates these errors will show.

Can anyone help me with these issues?

Thanks in advanced.

EDIT: This is the error in text form

- Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-+2fKGObejacuP4SLuObA8gksXdvQNO4noaRbPZ5NrT4='), or a nonce ('nonce-...') is required to enable inline execution.

- Blocked script execution in 'http://shoshaaustralia.com/vietkkong1975/admin/email_template/popup/key/f83b5572c102850cb106595be602...' because the document's frame is sandboxed and the 'allow-scripts' permission is not set.

Hi @tony_le2

Hi @tony_le2 

Please upload a better quality image. The errors can not be read as font is very small.

You may edit your question and update error message there in text form.

Hi @torhoehn 

what I did is make the height of the iframe as 100% or a fixed px and ignore the errors from the console. which will show the template correctly.

@tony_le2 Thanks for your answer! Maybe we had a different error with js minifying enabled. We applied this fix: https://github.com/magento/magento2/commit/e8eb43a84cb861cedda424aaf8be83aa1c6c1c29
