Rename transform fails on JSONB column

[bradnewman]

PGSync version: 2.1.7
Postgres version: 13.0
Elasticsearch version: opensearch:1.1.0
Redis version: 6.2.1
Python version: 3.9.7
Problem Description: When trying to add a rename transform for a JSONB column, PGSync raises an exception. Rename transforms on other columns work as expected, and the JSONB column is sync'd as expected if no rename transform is specified for it.

Error Message (if any):

  File "/home/appuser/.local/lib/python3.9/site-packages/pgsync/sync.py", line 720, in _payloads
    yield from self._sync(filters=filters, extra=extra)
  File "/home/appuser/.local/lib/python3.9/site-packages/pgsync/sync.py", line 844, in _sync
    row: dict = transform(row, self.nodes)
  File "/home/appuser/.local/lib/python3.9/site-packages/pgsync/transform.py", line 115, in transform
    data = _rename_fields(data, transform_node)
  File "/home/appuser/.local/lib/python3.9/site-packages/pgsync/transform.py", line 30, in _rename_fields
    value = _rename_fields(value, nodes[key])
  File "/home/appuser/.local/lib/python3.9/site-packages/pgsync/transform.py", line 43, in _rename_fields
    elif key in nodes.keys():
AttributeError: 'str' object has no attribute 'keys'

Can you please post the rename transform?

I've simplified the schema JSON to this, and the same problem occurs - unless I remove the group_tags -> tags rename transform:

[{
    "database": "db",
    "index": "groups",
    "nodes": {
        "table": "groups",
        "schema": "public",
        "columns": [
            "id",
            "name",
            "group_tags",
        ],
        "transform": {
            "rename": {
                "id": "groupId",
                "name": "displayName",
                "group_tags": "tags"
            }
        }
    }
}]

And the table is like this - though it admittedly does have more columns than this, I don't think it should matter:

CREATE TABLE public.groups (
    id uuid NOT NULL,
    name character varying NOT NULL,
    description character varying,
    group_tags jsonb
);

Thanks. This should be fixed now. Can you try using the master branch.

I've verified #212 resolves this issue - thanks!
