**Your software**  
My Mautic version is: 4.2.1, 4.2.2, 4.3.1  
My PHP version is: 7.4  
**Your problem**  
My problem is:  
Dynamic content does not seem to be working for me in any of these versions. Not in HTML or MJML mailers. When I send an email it just comes out Dynamic Content 2, and in 4.3.1 I do not even see the widget of Dynamic content.

So first I am interested in if anyone has it working for them.

Just tested this on Gitpod and I am seeing the same in that the dynamic content is not working, with the following error:

```auto
gitpod /workspace/mautic $ ddev exec bin/console m:c:t
Triggering events for campaign 1
Triggering events for newly added contacts
2 total events(s) to be processed in batches of 100 contacts

```

However I am getting the default content sent each time. I tried this with the Blank theme just to keep it simple.

Hey @silavapi

I went ahead and got our developer to make a quick fix for this. He did not do it inside the Mautic branch as we just wanted it working. So I have two files, one for Mautic 4.0.x - 4.2.x and a second file for 4.3.x and upwards. Maybe it can be used to help fix the issue in GitHub.

Here are the two pieces of code:  
For Mautic 4.0.x - 4.2.x MatchFilterLeadTrait.php

```auto
<?php

namespace Mautic\EmailBundle\EventListener;

/**
 * Trait MatchFilterForLeadTrait.
 */
trait MatchFilterForLeadTrait
{
    /**
     * @return bool
     */
    protected function matchFilterForLead(array $filter, array $lead)
    {
        if (empty($lead['id'])) {
            // Lead in generated for preview with faked data
            return false;
        }
        $groups = [];
        $groupNum = 0;

        foreach ($filter as $data) {
            $isCompanyField = (0 === strpos($data['field'], 'company') && 'company' !== $data['field']);
            $primaryCompany = ($isCompanyField && !empty($lead['companies'])) ? $lead['companies'][0] : null;

            if (!array_key_exists($data['field'], $lead) && !$isCompanyField) {
                continue;
            }

            if(is_null($primaryCompany) && $isCompanyField){
                continue;
            }

            /*
             * Split the filters into groups based on the glue.
             * The first filter and any filters whose glue is
             * "or" will start a new group.
             */
            if (0 === $groupNum || 'or' === $data['glue']) {
                ++$groupNum;
                $groups[$groupNum] = null;
            }

            /*
             * If the group has been marked as false, there
             * is no need to continue checking the others
             * in the group.
             */
            if (false === $groups[$groupNum]) {
                continue;

             * assume that the group will not match.
             */

                $groups[$groupNum] = false;
