Node.js v18.12.1

Start with the Primero adaptor's lib/Adaptor.js around line 317 and reproduce the getCases call using the openfn CLI command and Primero 2.7.0 shown in the logs. Trace why the successful 200 response leaves cases undefined; done means the command handles that response without the TypeError and reports retrieved cases correctly.
