### What happened?
I was trying to understand what labels a metric had. The …metric is counter. I changed the options to be an instant query so I could use a table to view the labels. When I ran the query, I got an error in the UI that didn't make much sense to me. I pulled out some of my very rusty Chrome debug tooling skills, and I found the location of the [exception here](https://github.com/grafana/grafana/blob/93fef224ae5d28100a47b37338c9ff18a52d0dc9/packages/grafana-prometheus/src/query_hints.ts#L53).
Error on the UI:

I could get around this by just adding rate to the metric. The error then goes away even though I only need an instant query.
### What did you expect to happen?
I expected to be given a metric with labels as I wasn't looking for more than a single data point and just wanted a table with labels of the single data point but instead, I was given an error in the UI.
### Did this work before?
Yes, I have used this many times before for work, but this was at my house and I hadn't seen it there before. I use watchtower to keep my Grafana updated and I am running the latest.
### How do we reproduce it?
1. Find a metric that is a counter
2. Change query to be an instance query but do not add rate
3. execute query and an error should happen
4. Refresh tab, add rate to metric and run again, there should be no error.
