Bug Error: Call to a member function appendChild() on null src/vendor/pelago/emogrifier/src/Emogrifier.php:1419

BigIron · Jul 17, 2019

We've got a couple thousand of these errors in my AdminCP after configuring the digest.

Code:

Some people have had success removing the Introduction text from the digest. As you can see, the error is not in this product but one of the libraries XF uses, so it’s unlikely a fix will be forthcoming soon.

I plan to report it as a bug in XF regardless, so they can kick it to the correct vendor.

BigIron · Jul 17, 2019

I'll give that a shot.

BigIron · Jul 17, 2019

That seemed to fix it, thanks @Fillip H.

Hopefully they'll fix it so we can use that feature.

Fillip H. · Jul 18, 2019

Out of curiosity, what was the intro text you used?

BigIron · Jul 18, 2019

The Northwest Firearms Digest is an email which is completely customizable to each users preference. Want to receive a list of new classified ads each day? It can do that. How about a list of the most popular threads only once a month? It can do that too. More information on these customizations can be found here.

Fillip H. · Jul 18, 2019

Okay, so the issue is likely with the usage of HTML.

Can you try instead of "here" being a link, just use the plain text link?

BigIron · Jul 18, 2019

I ran the Digest test and it looked like it worked without throwing an error.

Fillip H. · Jul 18, 2019

Interesting. This will be helpful when reporting the issue to XF, thanks

I'll make a note to disable HTML support for that area to mitigate the issue, since XF has just done a release so it would be quite a while until any fix for this would actually make it to XF itself.

BigIron · Jul 18, 2019

Good call, thanks @Fillip H.

BigIron · Jul 26, 2019

Just a heads up @Fillip H., I've left HTML out of the Introduction but received several of these errors when the digest was sent at 12:01AM.

I've posted the bug report: https://xenforo.com/community/threads/server-error-from-pelago-emogrifier-when-sending-email.168250/

Chris has asked for more information. Are you able to assist him? Thanks!

You can look back at my earlier report on this issue for another intro text example. I definitely did not use HTML. Might be of help.

It would be helpful if you could post it in the thread @ XenForo.com as I'm reasonably certain Chris D doesn't read these forums, that'd show him it's not an isolated case as well

Fillip H. · Aug 8, 2019

I've released an update that may or may not address this based on information gleaned from Chris' response: https://xenforo.com/community/threa...ifier-when-sending-email.168250/#post-1366860

If this doesn't work I'm gonna cry
