The job failed due to an invalid training file. 'str' object has no attribute 'get'

Hi!!
Thank You for the insight! so my entry should look like this?
{“messages”: [{“role”: “user”, “content”: “SIMLA FROZEN FOOD LOCKER LLC CO”}, {“role”: “assistant”, “content”: “Foodservice / Wholesale, retail”}]}

There is no way I can separate retail and wholesale/Foodservice at all? I do not want them to go as a single string, but I guess there is no other way to do it?? I want the model to be able to put multiple categories where its appropriate.
