We're using Bulk Api to upsert records for both Custom and Standard Salesforce Objects. Its working fine for custom objects but when We're trying to perform Upsert operation on a Standard Salesforce Object say: Account, the error of specifies Invalid External ID specified as:
[AsyncApiException exceptionCode='InvalidJob' exceptionMessage='Field name provided, Name does not match an External ID, Salesforce Id, or indexed field for Account' ]
We're providing Name as an external ID through java code.
