I am working on my first Salesforce Einstein Bot in a sandbox. The bot works well and navigates through multiple dialogs as intended until I try to call an Action. If I try to call any action, no matter how simple, the bot automatically ends the chat even though there are more steps in the dialog after the action call. I have even dumbed-down the invocable method to simply accept a string list and return nothing. The method literally does nothing and I can call it without issue from a Process Builder. For some reason in the bot it crashes the chat. I have deleted and rebuilt the bot from scratch with the same result.
Any thoughts or advice on what I might be missing? Suggestions on what else I can check?
Make sure to give your bot access to the apex class through permission sets. The bot has its own set of permissions name something like sfdc.chatbot.service.permset.
