Problem

The AWS Unified search service is very helpful feature that I often use to go to the AWS resource that I need to look at. but it’s suddenly broken since a couple of weeks ago.

Error Message

Unified search service is unavailable Try your search again later.

Solution

The issue is that I am using ModHeader plugin to access the Swagger page of my private API gateway. So I need to pass the x-apigw-api-id to see the private swagger page. I forgot to untick it so it was on all the time. (It means whenever I am accessing the website from Chrome, the ModHeader plugin will send the x-apigw-api-id in the http header. )

For some reason, AWS Unified search service doesn’t like it. So the solution is to untick the header in the plugin. And then it will work fine.
