Uptime-checking failing for PharmGKB registration

This isn't urgent.

I'm not sure why uptime-checking is failing for some endpoints (SmartAPI link), since they successfully run when I "try an example" using the example parameter values for those endpoints. I wondered if it had to do with the rate-limiting of this API (its documentation says it only accepts 2 requests / sec).

Marco noted that the failing endpoints have info like this: 🔴 /data/pathway: (400) {"status":"fail","data":{"errors":[{"message":"Missing criteria."}]}}

However, for those endpoints, no required parameters are missing an example value. For example, the /data/variantAnnotation endpoint has an example provided for every parameter....so these error messages are unexpected and confusing
