Web of Science API can return empty string

[edsu]

It appears that an API request can return an empty string instead of a JSON object.

Get the Web of Science API Key:

$ vault kv get puppet/application/sul_pub/prod/wos-api-key

Then try this request for ORCID 280000-0002-3271-7861:

$ curl --header "application/json" --header 'X-ApiKey: PUT_KEY_HERE' 'https://wos-api.clarivate.com/api/wos?databaseId=WOK&usrQuery=AI%3D%280000-0002-3271-7861%29&count=100&firstRecord=1'

And notice you get no output, but that it's a 200 OK. Once we figure out a reason for this we should adjust the rialto_airflow.harvester.wos.

We talked about emailing our contact at Clarivate to see if there is a reason that we are seeing this behavior. Otherwise this API route works fine.

Noting that @peetucket reports the curl command works for him. It looks like wos-api.clarivate.com resolves to multiple IP addresses so maybe I'm talking to one that works a bit differently?

$ host wos-api.clarivate.com
wos-api.clarivate.com is an alias for wos-api.prod1.prod.oneplatform.build.
wos-api.prod1.prod.oneplatform.build is an alias for api-pub.us-west-2.prod1.prod.oneplatform.build.
api-pub.us-west-2.prod1.prod.oneplatform.build is an alias for kongapi-prod-us-west-2.prod.sp.aws.clarivate.net.
kongapi-prod-us-west-2.prod.sp.aws.clarivate.net has address 44.225.8.221
kongapi-prod-us-west-2.prod.sp.aws.clarivate.net has address 35.155.244.135
kongapi-prod-us-west-2.prod.sp.aws.clarivate.net has address 44.228.82.11

Adding --verbose to the curl command highlights that I'm talking to 44.225.8.221:
