"study" projection request returns an unexpected error 500 response

Created by: ramiromagno

In the documentation docs/sample-scripts under the Section Searching and projections the link therein that leads to an API request using the study projection returns an unexpected 500 error:

curl 'http://www.ebi.ac.uk/gwas/rest/api/studies/GCST004364?projection=study' -i -H 'Accept: application/json'

returns a 500 error:

Without the "study" projection, we get a code 200 response for the same study accession (GCST004364):

curl 'http://www.ebi.ac.uk/gwas/rest/api/studies/GCST004364' -i -H 'Accept: application/json'
