Search vietnamese in elasticserch

I am installing plugin, but it appears an error like the image below. I could not continue to install it. Please tell me what the error is and why. thanks


Please don't post images of text as they are hard to read, may not display correctly for everyone, and are not searchable.

Instead, paste the text and format it with </> icon or pairs of triple backticks (```), and check the preview window to make sure it's properly formatted before posting it. This makes it more likely that your question will receive a useful answer.

It would be great if you could update your post to solve this.

I have updated the post, thanks for the comments.
