Email not being sent

[tmertz]

I am seeing a problem with sending email.

The logs say: Trying to access array offset on value of type null

I really have no idea on where to begin to debug this.

[freescout-helpdesk]

Please send full error message

[tmertz]

That is all the log is showing me? Where so I find the full error?

[tmertz]

I found a little bit more.
I have about 147 rows of this:
Trying to access array offset on value of type null; File: /home/witchards/sites/help.witchards.com/public/vendor/egulias/email-validator/EmailValidator/Parser/Parser.php (147)

And the laravel log says:
Trying to access array offset on value of type null {"exception":"[object] (ErrorException(code: 0): Trying to access array offset on value of type null at /home/witchards/sites/help.witchards.com/public/vendor/egulias/email-validator/EmailValidator/Parser/Parser.php:147)

[freescout-helpdesk]

Does it happen for all outgoing emails or just for some customers? Can you give examples of email addresses?

[tmertz]

It happens for all emails except emails send using the testing tool.
Doesn't matter if its gmail, yahoo, hotmail, etc.

[freescout-helpdesk]

Have you tried to clear the cache in Manage --> System --> Tools?

[tmertz]

Yes. I've cleared that cache a couple of times, to no avail.
In a fit of desperation (we have several players desperately needing to hear from us), I went into the dependency and changed the method to always return false, and that somehow solved my problem. Presumably something is being passed to that method that makes return true and upon returning true it kinda shits the bed. :D

[tmertz]

Updating to latest version only returns the error. Which is not surprising as it is simply running composer update presumably, and thereby overwriting the change I made to the dependency.

@freescout-helpdesk I'm facing a similar error. Test emails go fine. However, My replies/outgoing emails are not being sent and I've to force-fetch all incoming emails. Please help.

[freescout-helpdesk]

Sorry, we can't reproduce the issue on our end.

[sam-suresh]

I got same error after moving site from Vultr to DO.
Using same Apache+Nginx stack.

Still checking what is wrong.

Partial finding: PHP 7.4
This version of Laravel supported up to 7.2 only
laravel/framework#30737

I'm using 7.2 now but the issue still there.

[freescout-helpdesk]

If anyone can provide us access to your server to check this issue please email at [email protected]

[uaimax]

I'm facing the same issue. Just sent the ssh access to email.

[freescout-helpdesk]

I'm facing the same issue. Just sent the ssh access to email.

Are you using the latest version of FreeScout?

[sam-suresh]

Confirmed in the present version the issue still exists.
Tried to switch PHP 7.2, 7.3, and 7.4 still the same.

[sam-suresh]

Looks like this is related to the email validator package.
Although the original issue affecting PHP 7.4, FreeScout PHP 7.2 affected too.
egulias/EmailValidator#203

Omitting the following line, stops this error and the app working. I'm not sure how this affects though.

       // $previous = $this->lexer->getPrevious();
        // if ($previous['type'] === EmailLexer::S_BACKSLASH
        //     &&
        //     $this->lexer->token['type'] !== EmailLexer::GENERIC
        // ) {
        //     return true;
        // }
        // return false;

[freescout-helpdesk]

Make sure that your console PHP version is < PHP 7.4:

php -v

[sam-suresh]

You are absolutely right! Although I set PHP version for FreeScout app, the composer always using PHP-CLI

on Ubuntu,
sudo apt-get install php-cli
sudo dpkg-reconfigure php-cli

then downgrading to PHP 7.3 solved the issue!!

[freescout-helpdesk]

Great.
