Truncate paragraph

I am trying to truncate a paragraph but it generate an empty p.

<p class="card-text" dmx-html="blog_blog.trunc(120, 'true', '...')"></p>

When I am trying this

<p class="card-text" dmx-html="blog_blog"></p>

it is working

There is no issue with this code:

<p class="card-text" dmx-html="blog_blog.trunc(120, 'true', '...')"></p>

How did you add this - was it through the UI? If no - then maybe the formatter js is missing from the page.

I have added it through UI

Ok, do you see any errors in the browser console?

I think nothing serious

Do you have a live link where i can see your page?

Unfortunately no
