Hi @GeoffOD , this error is seen when the schema (schema_v23) is specifically passed as an empty string. The possible values of schema for Shopify are REST-2023-04, REST-2023-07, GRAPHQL-2023-04, and GRAPHQL-2023-07. If no value for schema is passed while creating the connection, a default value of REST-2023-04 is taken. Can you please specify the schema as one of these for creating the connection?
Thanks!
