Description
Pasting a polldaddy link into the gutenberg editor does not result in an oembed.
To Reproduce
Steps to reproduce the behavior:
Expected behavior
I was expecting a preview of the poll to appear.

We should make our own products work with this :)
Just tried with these two links:
And it works for me in both cases?
@youknowriad I'm expecting to see this while I'm editing the post in gutenberg not just after publishing.
Is that an incorrect expectation?
yes, it is. Here's a GIF of what I'm doing.

Notice that the embed appears as soon as I paste
Hmm - seems this might be related to just our p2s :) cc @designsimply
I'm closing for now, Let's reopen if it comes up in a more generic installation.
I am able to confirm this bug with Gutenberg 3.4 using a site with HTTP. Steps to reproduce:
Sample code:
http://polldaddy.com/poll/10073993/[polldaddy poll="10073993"]http://poll.fm/5zx55Result: embed does not work, a console warning appears on the editor screen, and the poll is blank on the front end after publishing and viewing the post.
Console warning after pasting the poll URL in the editor:
Loading failed for the <script> with source “http://static.polldaddy.com/p/10073993.js”.
Resulting HTML in the block:
<figure class="wp-block-embed is-type-rich is-provider-polldaddy">
http://polldaddy.com/poll/10073993/
</figure>

I'm not re-opening yet because it may be fixed in master but not 3.4 and that still needs double checking.
I'm also running an HTTP site, so this is probably something else. Any idea @notnownikki ?
@designsimply It worked for me on HTTP using the poll link you posted above on 3.4 and also on master. Did you try to pull up the JS file directly from the error message and seeing if it worked independent from WP?
(Also hi @annezazu! 😄 )
Just tested with http://polldaddy.com/poll/10073993/ and it's showing up for me, the embed render endpoint doesn't have any issue.. My development site is also HTTP.
@designsimply What's interesting is that the shortcode [polldaddy poll="10073993"] isn't working for you, that suggests either something isn't getting processed correctly in the WP core side, or that there's some intermittent problem on the Polldaddy side. I think this is most likely a Polldaddy or network problem, as the embed is trying to load the assets, but as I can see from your console output, the script wasn't loaded. To make doubly sure, can you open the network tab and see what response you got for that script?

Absolutely! I re-tested and found that the script response looks good (in both Chrome and Firefox!) _but in Firefox_ the embed does not show up inside the editor (same as before). Here's a comparison: 1m28s.

Here are the console errors from Firefox:
