uncaught TypeError: t.getTransformToElement is not a function

[anhk]

I got this error at mermaid.min.js:5 in browser chrome.
I'm using hugo as the web server, and my markdown content is:

<div class="mermaid">
graph LR
    A-->B
</div>

finally hugo will generate html page like:

<div class="content">
  <div class="mermaid>
graph LR
   A-->B
  </div>
</div>

as a result, I got this error:

uncaught TypeError: t.getTransformToElement is not a function
