Hello @samuelecarpene , we were unable to reproduce this issue, can you provide additional information?

scottsb commented 6 years ago

We saw the same issue. I wasn't able to identify the pattern exactly, but it seemed to happen after a deploy. I'm not sure if it's the recompliation, static deploy or cache flush that would trigger it. After a few page loads it would seem to go away.

I think I know where problem is. Your plugin is applied too deep on Zend Response guts where Magento area code is not set yet at least in production mode.

jefflenz commented 6 years ago

Same issue. Disabled this module and my store works now.

phoenix128 commented 6 years ago

Yes, the issue is confirmed on 2.2, we are working on that

magefan commented 6 years ago

the same issue with the extension when enabling maintenance mode.

phoenix128 commented 6 years ago

So sorry for making you wait for so long time. We had crazy time :) Thanks to @maqlec , this issue should be fixed.

cavalier79 commented 6 years ago

Does this issue have been solved? We also need it. Thanks!

I had the same issue today: When the maintenance mode is enabled (in either Production Mode or Developer Mode) this error pops up, hiding the actual message that is given by the maintenance mode itself.

However, I don't think this necessarily needs a fix: In the Developer Mode, you don't need a maintenance mode - perhaps the docs of DevTools could just give a hint that the maintenance mode doesn't work well with the DevTools extension. And in the Production Mode, you should not use the DevTools extension anyway! The extension should be added to the require-dev section, not the require section.

We also experience this issue on our development sites, we run 2.3.1. The issue occurs every time we perform a setup:upgrade or a cache clean. It also prevents us from accessing the admin side of our site.

VernonGrant commented 5 years ago

After you set bin/magento maintenance:enable in both development or production, this error is thrown.

Any update on a fix for this :)
