Error-Output.txt

AOE\Crawler\Tests\Functional\Controller\CrawlerControllerTest::expandExcludeStringReturnsArraysOfIntegers
Symfony\Component\DependencyInjection\Exception\RuntimeException: Cannot autowire service "AOE\Crawler\QueueExecutor": argument "$crawlStrategy" of method "__construct()" references interface "AOE\Crawler\CrawlStrategy\CrawlStrategy" but no such service exists. You should maybe alias this interface to one of these existing services: "AOE\Crawler\CrawlStrategy\GuzzleExecutionStrategy", "AOE\Crawler\CrawlStrategy\SubProcessExecutionStrategy".

How did you solve the error?

Do you have a link to where I describe the problem? The gist alone is't ringing any bell for me unfortunately.
I will remember the next time to ask in the gist as well adding the solution.

sorry, no. I just found this gist through a search engine.

I found it from a twitter search for the url:
https://twitter.com/tomasnorre/status/1315330213018992643

I cannot complete recall, but reading through the commits I think this was the change I did to fix my problem.
