GCP Service Account Key Rotation

I am trying to implement Key Rotation for GCP Service Accounts. I have managed to create a new key and then decode the privateKeyData which is base64 encoded, which has the actual SA JSON file. Now when I am reading the file back to authenticate, it is giving me this error:

'unicode object has no iterKeys()'

Issue is with json.dumps I think.

data = base64.b64decode(key['privateKeyData']).decode('utf-8')
print data  # this prints expected output


with open('file.json', mode='w') as out:
    str = json.dumps(data)
    print out  # this adds \n,\\ to the output
    out.write(str)

Error:

AttributeError: 'unicode' object has no attribute 'iterkeys'

Dummy Snippet of how the file is being converted after json.dumps:

"{\n  \"type\": \"service_account\",\n  \"project_id\": \"testproj\",\n  \"private_key_id\": \6866996939\"}"\n

The json.dumps() function is usually used to turn a dict into a string representing JSON:

>>> json.dumps({"foo": "bar"})
'{"foo": "bar"}'

But you're giving it a string instead, which is causing it to escape the quotes:

>>> json.dumps('{"foo": "bar"}')
'"{\\"foo\\": \\"bar\\"}"'

You should just write data to the file instead:

with open('file.json', mode='w') as out:
    out.write(data)

It seems you might have a second problem that is causing the exception, you should include the full traceback in your answer, instead of just the last line.
