Error: TypeError: string indices must be integers

New to python, trying to convert json file to csv and wrote below code but keep getting "TypeError: string indices must be integers" error. Please suggest.

import json
import csv

#x= '''open("Test_JIRA.json","r")'''
#x = json.load(x)

with open('Test_JIRA.json') as jsonfile:
    x = json.load(jsonfile)

f = csv.writer(open("test.csv", "w"))

# Write CSV Header, If you dont need that, remove this line
f.writerow(["id", "self", "key", "customfield_12608", "customfield_12607"])

for x in x:
    f.writerow([x["id"],
                x["self"],
                x["key"],
                x["fields"]["customfield_12608"],
                x["fields"]["customfield_12607"]
                ])

Here is sample 1 row input json file data:

{"expand":"schema,names","startAt":0,"maxResults":50,"total":100,"issues":[{"expand":"operations,versionedRepresentations,editmeta,changelog,renderedFields","id":"883568","self":"https://jira.xyz.com/rest/api/2/issue/223568","key":"AI-243","fields":{"customfield_22608":null,"customfield_12637":"2017-10-12T21:46:00.000-0700"}}]}

As far as I see problem is here

for x in x:

Note, that x in your code is a dict, not list. I think (based on provided json example) you need something like

for x in x['issues']:

Also, @Reti43 note in comment, that keys of dicts in x['issues'] vary between elements. To make your code more safe you could use get

for x in x['issues']:
    f.writerow([x.get("id"),
                x.get("self"),
                x.get("key"),
                x.get("fields", {}).get("customfield_12608"),
                x.get("fields", {}).get("customfield_12607")
                ])
