Welcome to Microsoft QnA!
I see your issue is with Uploading your Data to Open AI
Allow me to ask some things , may seem obvious but please clarify as much as possible;
Do you have the Cognitive Services OpenAI Contributor Role ( or User) in the OpenaI Resource ?
Can you try with the Data i am providing ? Look attachement
Let me know how it went !
I hope this helps!
