Error happening in Categories Admin

[nico-gandara]

We have a Magento 2.2 site, with Elastic Suite. Not sure why, but we have had this error a couple of times.

We don’t have a sistematic way to reproduce it. When the error starts happening, it happens all the time.

to explain it a bit better: it happened once in our QA environment, and we are not sure why, but it “solved itself”. Now we are installing our website in the environment that will be production, and it is ocurring again.

What we can tell you are details that we see when the problem occurs. Hope this helps to understand it

Magento Version : 2.2.0 EE
ElasticSuite Version : 2.5
Environment : Production
Third party modules :nono

Steps to reproduce

1 Go to Menu, catalog, categories.
2. We see a stuck page
3. Opening the browser inspector, we see the following errors:
4. Stack Trace:

Hi @ngandara-summa,

Think your problem is a duplicate of #748, #787 and #836.

Can you confirm increasing max_input_vars solve it ?

Close since PR #880 have been merged in branch 2.5.9 and a workaround is proposed.

Hey Guys,

debugged myself into this and found a possible bug/solution.
In my project i was extending the Magento\Catalog\Model\Category and replaced it with a <preference .../>

Removing this preference, clearing all caches and generated classes, this works like a charm ^^
