Encountered this error while saving sales order that has workflow that sends email to sales rep .

{"type":"error.SuiteScriptError","name":"SSS_AUTHOR_MUST_BE_EMPLOYEE","message":"The author internal id or email must match an employee.",

but the sales rep assigned is an employee.. what could be the reason

Your message relates to the Author not the recipient...

yeh i guess , a restlet script is executing the workflow

I don't know, maybe ask in suiteflow, I somewhat assumed you were using a workflow action script as you were asking in suitescript channel. I rarely create or modify workflows, not really my thing 🙂

yup , I selected that there is no option i guess. I just set a specific sender and problem seems to be solved . Error was showing up when i was creating a sales order with a script. Thanks alot for help 👍

If you want it to be dynamic, you will need a custom field to store the author of the email and update the workflow action to get it from the custom field.
