2.2.6+ has an undeclared dependency on newer versions of GuzzleHTTP, breaking D9

Created on 22 August 2025, 11 days ago

Problem/Motivation

Unfortunately, we've still got some clients on Drupal 9. The latest two releases for mailchimp 2.x in late July introduced an undeclared dependency on a newer version of GuzzleHTTP that wasn't backward compatible, resulting in the following error when we did our monthly updates:

The website encountered an unexpected error. Please try again later.
Error: Call to undefined method GuzzleHttp\Utils::defaultUserAgent() in _mailchimp_get_user_agent() (line 79 of modules/contrib/mailchimp/mailchimp.module).

Steps to reproduce

Upgrade any D9 site to mailchimp 2.2.6 or newer.

Proposed resolution

The workaround was to revert to 2.2.5. mailchimp.module contains the following code at line 79:

$user_agent = "DrupalMailchimp/$version " . Utils::defaultUserAgent();

Prior to that, it was this:

$user_agent = "DrupalMailchimp/$version " . default_user_agent();

We need some kind of wrapper on that to determine whether the new method exists before attempting to use it, falling back to the old one if it does not (or vice versa).

Remaining tasks

Write a patch (I'm on it). 🤣

    These errors don't read like anything of mine (I barely touched anything 🤣) - gonna need some input on this, but I wonder if these were failing already?

    Ah, good catch. Will your fix work without the

    use function GuzzleHttp\default_user_agent;

    line?

    The failing tests are not likely to be your fault -- they need a lot of work.
