Description

Tell us about why this change is necessary:

• Are you fixing a bug or providing a failing unit test to demonstrate a bug?

on php 7.3 i'm getting fatal error interface not found in Client.php
doing proper import of interface

• How do you reproduce it?
  error actually happened with old zend http, but it said dont accept new contributions,
  and i see code looks same in laminas

Not a bug. Check your local environment for issues. Explicit composer dump-autoload to recreate autoloading files fixes such issues in most cases.

Check if you have some laminas packages installed (composer show | grep "laminas") then make sure you use latest composer (1.9.2) as there were issues reported with older versions not registering autoloading properly on package rewrite by plugin. If you have laminas packages installed then makes sure to do composer update after you updated composer

I will accept this as QA but remove the test as redundant.

I just upgraded php version, so yeah might have forgot to dump-autoload.
