API - unknown field name error 422

I am getting a 422 error code when I try to update a record via PATCH method. Specifically, the Airtable > Update a record event performs the folloiwng HTTP request:
curl -X PATCH ‘https://api.airtable.com/v0/APPXXXXXX/Clients/RECXXXXXX’ -H ‘user-agent: Integromat/production’ -H ‘authorization: ***’ -H ‘content-type: application/json’ -d ‘{“fields”:{“Status”:“Lead - New”,“Initial Call Date”:“2020-04-16”,“Post Call Followup”:“None”,“Opportunity Followup”:“None”,“Post Project Followup”:“None”},“typecast”:false}’
for which the module received the following response:

Status code: 422

The API call keep throwing the UNKNOWN_FIELD_NAME error despite the fact that the field Status evidently exists in the referenced table. I am getting this error for OTHER fields as well.

A wild guess - the double quotes in your JSON payload trouble me. Make sure you don’t have a character encoding issue in your cURL statement.
