ebizmarts_ecommerce has an error

[vDeggial]

Magento 2.2.8
Mailchimp: v101.2.36
For last few hours this has been happening and nothing is synced to Mailchimp:

[2019-06-20 00:15:26] main.ERROR: Cron Job ebizmarts_ecommerce has an error: Warning: Invalid argument supplied for foreach() in /home/jri/public_html/vendor/mailchimp/mc-magento2/Helper/Data.php on line 1037. Statistics: {"sum":0,"count":1,"realmem":0,"emalloc":0,"realmem_start":134217728,"emalloc_start":128640120} [] []
[2019-06-20 00:15:26] main.CRITICAL: Warning: Invalid argument supplied for foreach() in /home/jri/public_html/vendor/mailchimp/mc-magento2/Helper/Data.php on line 1037 {"exception":"[object] (Exception(code: 0): Warning: Invalid argument supplied for foreach() in /home/jri/public_html/vendor/mailchimp/mc-magento2/Helper/Data.php on line 1037 at /home/jri/public_html/vendor/magento/framework/App/ErrorHandler.php:61)"} []

The problem indicates that issue is around the lines of:

$api = $this->getApi($storeId);
            $listId = $this->getConfigValue(self::XML_PATH_LIST, $storeId);
            $allInterest = $api->lists->interestCategory->getAll($listId);
            foreach ($allInterest['categories'] as $item) {
                if (in_array($item['id'], $interest)) {
                    $rc[$item['id']]['interest'] = ['id' => $item['id'], 'title' => $item['title'], 'type' => $item['type']];
                }
            }

which maybe tells that there is an issue with API ... or the plugin (which have not been changed in any way)

It seems that only Orders sync is affected, Subscribers seem to be syncing fine ...

Try to put the foreach that way:

            if (array_key_exists('categories',$allInterest) && is_array($allInterest['categories'])) {
                foreach ($allInterest['categories'] as $item) {
                    if (in_array($item['id'], $interest)) {
                        $rc[$item['id']]['interest'] = ['id' => $item['id'], 'title' => $item['title'], 'type' => $item['type']];
                    }
                }
            }

That gives a new error:

Is so weird, what if you use curl from the command line like say here?

https://developer.mailchimp.com/documentation/mailchimp/reference/lists/interest-categories/#read-get_lists_list_id_interest_categories

specifying your list of course

[gonzaloebiz]

perhaps a cache issue?
Change this line https://github.com/ebizmarts/mailchimp-lib/blob/master/src/Mailchimp.php#L226 for this

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Cache-Control: no-cache'));

still same error after that change :( Could it be related to Godaddy VPS screwing things up again (they did before with dif issue and we had to rebuild the server as they didnt want to help)? It just randomly started yesterday afternoon ...

[vDeggial]

I commented out that code in Data.php that gave errors (it relates to list intersts anyways which we dont have) and all syncing fine now lol

/*
            $api = $this->getApi($storeId);
            $listId = $this->getConfigValue(self::XML_PATH_LIST, $storeId);
            $allInterest = $api->lists->interestCategory->getAll($listId);
            if (array_key_exists('categories',$allInterest) && is_array($allInterest['categories'])) {
                foreach ($allInterest['categories'] as $item) {
                    if (in_array($item['id'], $interest)) {
                        $rc[$item['id']]['interest'] = ['id' => $item['id'], 'title' => $item['title'], 'type' => $item['type']];
                    }
                }
            }
            foreach ($interest as $interestId) {
                $mailchimpInterest = $api->lists->interestCategory->interests->getAll($listId, $interestId);
                foreach ($mailchimpInterest['interests'] as $mi) {
                    $rc[$mi['category_id']]['category'][$mi['display_order']] = ['id' => $mi['id'], 'name' => $mi['name'], 'checked' => false];
                }
            } */

upon upgrade to Magento 2.2.9 and reinstalling the plugin all works fine without the modification ... weird :(

[gonzaloebiz]
