update_schema API returns KeyError

[vrajat]

Couple of issues:

1. update_schema() is adding a default schema but the return seems to be failing:

Traceback (most recent call last):
  File "~/Library/Application Support/Sublime Text 3/Packages/User/lin_test.py", line 46, in <module>
    catalog.update_source(source,schema)
  File "~/Library/Python/3.8/lib/python/site-packages/data_lineage/__init__.py", line 489, in update_source
    attributes=payload["attributes"],
KeyError: 'attributes'

Code executed:

source = catalog.get_source("rs")
schema = catalog.get_schema("rs", "test")
catalog.update_source(source,schema)

2. Query is sent to the server for parsing but no update in UI and also no logs generated on lineage app as well.

Last line from visualizer log:
10.10.0.1 - - [16/Jul/2021:15:53:08 +0000] "POST /api/v1/parse?query=<query>&source_id=7 HTTP/1.1" 200 181 "-" "python-requests/2.25.1"

*removed the query as its pretty long
