Hello @Tauseeef,

It will be great if you describe your position in a better way like what version of Tutor you are using, What steps you have done till now, etc.

Please provide this information so that people here can check and help you.

The error is occurring while I try to search the course from UI, I have enabled the discovery plugin and intialized it as well.
the error occurred when I tried to deploy koa but even if I go with simple images from overhang registry , I do not get any exception but search still gives me error that “We couldn’t find any results for “demo”.”.

Anything that I am missing here ?

I am getting above error in discovery startup logs , any idea where to define this ELASTICSEARCH_DSL
?

@Tauseeef you really need to tell us which tutor version you are running, along with which plugins. Also, describe how you customised your platform. You mention that you are running Koa: are you aware that Koa is only supported for tutor less than v12?
