email no longer sent after editing newPost.blade.php

Averell

Hello,
I broke something somewhere when I tried to edit :
flarum\extensions\flarum-subscriptions\views\emails\newPost.blade.php
to translate the "Follow" e-mails in French. Probably it should have been written in Utf8 because now something is broken. The system is no longer able to send emails, because of this error :

Unable to encode data to JSON in Zend\Diactoros\Response\JsonResponse: Malformed UTF-8 characters, possibly incorrectly encoded

Strangely enough, it has nothing to do with the program itself because I installed a brand new Flarum and then connected to the database. The same problem happens. So, it should be something in the database, but what and where ? I have been unable to discover.

I tried with another browser, I tried in a private window. the same error happens.
It happens when email is sent for followed message, or for changing the password or things like that.

If anyone has an idea of the possible location of the error.

Franz

Can you show us the full stacktrace for the exception, please?

Averell

Well, it's a long one. Here it is.

Franz Swift_TransportException

Averell can you post the contents of the blade file you edited?

Franz

This seems to be happening when making a post, correct? Does the post contain any strange characters that could be causing this issue?

Averell

@luceos , investigation is proceeding and I am now almost convinced that it is a bug in Flarum, and has nothing to do with the modification I made (I came back to the standard file at once). I am trying to reproduce the bug in a new, unmodified, installation.

Averell

Presently the result is that it has something to do with a faulty smtp configuration (Encryption set to TLS, but I don't use TLS). When I switched to "mail" the bug disappeared. Unfortunately, when I came back to the faulty smtp parameters, the bug did not come back ! So my installation is now working, but I don't know the exact reason of the bug 🙁
Probably an error message from the mailer which had something that POST didn't like. But what ? Presently I don't know.
If the bug comes back, I'll tell you

What is strange : In the last tests, it was clear that the bug appeared on some particular discussions and not on others (stable : always or never). Since the message in the test discussions was three words, and everything was OK in the database, I am unable to understand what triggered the bug in one case and not in the other.

Averell

@Franz , to answer your question about the blade file.

This example works (french translation), provided it is written in utf-8, otherwise you have ? instead of accentuated characters. :

Bonjour, {{ $user->username }}!

{{ $blueprint->post->user->username }} a écrit un message dans une discussion que vous suivez : {{ $blueprint->post->discussion->title }}

Pour voir les dernières nouvelles de cette discussion, suivez le lien ci-dessous:
{{ app()->url() }}/d/{{ $blueprint->post->discussion_id }}/{{ $blueprint->post->number }}

=============================================================
{{ strip_tags($blueprint->post->contentHtml) }}
=============================================================

Vous ne recevrez pas d'autre notifications concernant cette discussion, tant que vous n'aurez pas été la consulter.

There is a problem about : strip_tags($blueprint->post->contentHtml)

I don't know what it is expected to do, but the result in Thunderbird is this (example) :

   ===========================================================
   Pour l&#039;instant rien re&ccedil;u de la derni&egrave;re
   =============================================================

Which is not beautiful ! The line expected is :
Pour l'instant rien reçu de la dernière.
I have tried to put html codes like <b> but they are not interpreted, they just appear like this.

I tried to start the file with : <!DOCTYPE html>. No result.
I tried to start the file with :

Content-Type: text/html; charset=UTF-8
<html>
....
</html>

No result (the text is displayed as is)

None of these tests provoked an error.
