Some error in config.yml.sample?

It did happen to my website, causing my website to throw a 500 error that I couldn’t find out, after commenting out this line, the problem was fixed.

( Apache PHP-FPM SSL , API in Docker )

the key "- "

What was the exact error message?

chrome header : 500 internal server error @ apache ,
but no any log content by apache or php , so the question from api I think

When I visit api :3456/api/v1/info , I got same error , like { internal server error }

If the error is caused by the api there should be an error in the api logs.

PHP is completely irrelevant here, the api does not use it.
