Salesforce plugin: Imported schema is not a valid Avro schema

Salesforce plugin can't retrieve schema from Salesforce for the following SOQL Query:

select id,Product2.id,unitPrice,Order.accountId,Order.effectiveDate,Order.type,Order.Account.currencyIsoCode,Order.BillToContact.email,Order.ActivatedBy.alias from Orderitem

The error message is: "Imported schema is not a valid Avro schema: Error: invalid field name: Product2.id"

Most likely it can't convert the column names into valid avro schema name since "." is not allowed
