Drupal 8.6.x issue: TypeError: Argument 2 passed to Drupal\page_cache\StackMiddleware\PageCache::storeResponse() about lscache-drupal

I don't know why it's not returning a response when it's not cacheable.
@usmannasir it is a missing case ?

It seems Drupal internal cache is in play, do you have LSCache module active as well? If so, does the error go away if you disable the LSCache plugin?

@usmannasir if I disable/uninstall the LSCache Module the issue is gone

The patch from @Bahlaouane-Hamza shouble be merged from our point of view. Our developers crafted a similar patch them selves to be able to get the module in production on a customer website. Not 100% sure if there any side effects though.
