我收到了这个错误:
Error:Read-write mappings require an upsert field for syncing. Upsert fields must be defined as unique External ID fields in Salesforce.More Info...
Warning:Fields needed for insertion to Salesforce need to be mapped: LastName
在 Heroku 中为 Contact 对象创建映射时,将计划从 Developer 更改为 Professional。
即使更改为高于 Professional 的计划,也会出现相同的错误。
开发者计划是可能的。
