Thanks for reaching out to us, this error happens when you have no correct role to deploy the model.
It seems your admin did not set your role correctly to get the access for deployment, please go to Azure Portal to check what role you have. Typically, you need to at least have a Cognitive Services OpenAI Contributor role for making a deployment.
Please have a try and let me know how it works. Let us know if you have any questions.
