Studies Rest API Endpoint to Get One Study Detailed Data

As developer I want a study details API endpoint such that when I send a GET request to the URL I can get full details of a single study in JSON Format

This will be a replacement to the old endpoint https://www.ebi.ac.uk/gwas/rest/api/studies

{
  "initialSampleSize": "...",  
  "replicationSampleSize": "2,698 European ancestry Bipolar disorder cases, 1,649 …",
  "gxe": false,
  "gxg": false,
  "snpCount": 1922309,
  "qualifier": null,
  "imputed": true,
  "pooled": false,
  "studyDesignComment": null,
  "accessionId": "GCST000854",
  "fullPvalueSet": false,
  "userRequested": false,
  "pubmedId": "20971583",
  "platforms": [{}],
  "diseaseTrait": "Suicide risk",
  "genotypingTechnologies": [{}],
  “efo_uri”: "EFO_0004229",
  “efoTrait”: "Dupuytren Contracture",
  "_links": {
    "self": {
    "href": "{base_url}/v1/studies/GCST000841"
    },
    "ancestries": {
    "href": "{base_url}/v1/studies/GCST000841/ancestries"
    },
    "search": {
    "href": "{base_url}/v1/studies?pubmed_id"
    }
  }
}

Must Have Additional Payload Attributes - These are displayed on the catalog UI:

discovery_ancestry (country of recruitment): "4390 European (U.K.)"
Traits: ["mental or behavioural disorder", "attempted suicide"]
Platform [SNPs passing QC]: "Affymetrix [1922309] (imputed)"
Replication ancestry (country of recruitment): "1649 NR (NR), 2698 European (Germany)"
Full Summary Statistics: "NA"
Terms/Licence: "https://www.ebi.ac.uk/about/terms-of-use/"
backgroundEfoTraits: ["",""]

Management Rules

Rule 1: Endpoint - /v1/studies/{accessionId}
Rule 2: HTTP Request Method - GET
Rule 3: Endpoint should accept studies id
Rule 4: Endpoint should return full attributes of the studies
Rule 5: Endpoint should be accessible to all

Acceptance Criteria

Given a correct accession Id
When the front end sends a GET request to the endpoint
A single corresponding study is returned in JSON Format
Given a wrong study id
When a GET request is sent to the endpoint
Properly described Resource not found exception error should be returned as JSON payload
