Getting Unknown validation error while authoring experience fragment component

[supriya-hande]

In our project there is header experience fragment(xf) and inside that we have authored Header component. This header component internally adds experience fragment component using data-sly-resource and path to our experience fragment component. We are authoring path of notification XF into this experience fragment component. 
I deployed this code in dev and stage server and there I can author path of notification XF into this experience fragment component but same thing is not working on stage. I am getting Unknown validation error as below

anyone know why this is happening? Appreciate your help.

Hi @supriya-hande ,

You need to check your browser console to get more details about this error.

Also, check the error.log of AEM to see if something is wrong with the authored experience fragment.

Hi @nitesh_kumar 

I am getting this error in console: POST https://domain-url.adobeaemcloud.com/bin/wcm/experiencefragments/verifyreferences.json 400

Any idea why this error comes.

This looks like due to a circular reference of experience fragment in your implementation which causes heavy performance issues, A fix to this was released which might be causing this error.

I also suggest to open a case with Adobe.
