Hello @sateesh285,

First of all, please respect the issue template and provide detailed information about your environment (versions of Magento and ElasticSuite) and steps to reproduce the issue. Otherwise, it's unlikely someone from our team will have a look at it.

Most probably something is wrong on your side, but at this moment it is hard to say what can be the reasons of your problem. We need more information about your environment.

Have you checked Magento and Elasticsearch logs or in the Console tab of your browser?

BR,
Vadym

Magento: 2.4.6-p5

ElasticSuite: 2.11.8.3
elasticsearch ver. 7.17.23

@vahonc Any update. We are eagerly waiting for your response

[vahonc]

@sateesh285,

Are you sure that the difference between your environments is only in the number of products or maybe there is a difference in the config settings?

Can you provide what you have as below:

BR,
Vadym

[sateesh285]

It is Product Name for our Case

[CalzaFino]

Just a comment:
My store was working fine but after I made a couple of redirects in Nginx, I started having this same issue. I just removed those new redirects and the error disappeared.

[vahonc]

@sateesh285

We added a couple of fixes in the last release of Elasticsuite. Can you check if your issue is still occurring after updating?

BR,
Vadym

[sateesh285]

Thanks for the fix. After update all issue got fixed.
