Query to database stopped working

As of last Friday, all my queries were working. This morning though, I tried running a query that works in my query bench against my local AND developer versions of Couchbase, and it doesn’t work. The error I get is: “Error processing JSON request body - cause: unable to parse JSON”. It is error 1040. Can someone please help me? I’m running the Query function from my Go codebase - that function used to work fine before, but as of today it seems like it’s broken or something…

This is the log I get in my Couchbase UI btw:
