Error when pushing lead to Mailchimp
Hi there. Newbie Here. Having an issue pushing a lead to mailchimp. Have successfully linked to the mail chimp api with the api key and it has successfully recognised each of my mail chimps lists.
However When choosing an Action in the campaign or form builder, i get a 500 error and can no longer continue.
The error log is as below.
I’m using Mautic 2.8.0 with PHP7.
Can anyone assist?
Code:

Hi,
I can reproduce this exact same issue on a fresh Debian 8 installation with Apache2 and PHP5. To reproduce, it is not needed to actually have a Mailchimp account, just activate the plugin and enter some gibberish in username/password fields.

Hi, folks! Upvoting this. I had the same issue with error 500. I’m using Mautic Cloud Free.
Tks and best regards!

@rbaffoe: I think the link should be: [https://github.com/mautic/mautic/issues/4037](https://github.com/mautic/mautic/issues/4037)
Isn’t the combination Mautic and MailChimp used so much?
I am wondering that this bug still exists and hope that it will be fixed soon.
Is there at least an ETA for that?

Hi,
I also registered at [icontact.com](http://icontact.com) to integrate that, but there is also the same error 500 on the Mautic admin page and with the same error in the log file:
> [@](#):
>
> mautic.CRITICAL: Uncaught PHP Exception SymfonyComponentOptionsResolverExceptionUndefinedOptionsException: …
Is there a known integration, that works with the actual version, with a trial account to test this on private pages?
Edit: I also tried [Zapier.com](https://autoize.com/zapier-integration-mautic/), but there isn’t any contact from Mautic in MailChimp yet. After editing the Template for MailChimp I get an error “Required fields without a value: Subscriber Email” when testing it in the next step.
