Hi @Kaïss Berkani Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.
I see that you are facing error when redeploying a service bus. I wanted to check if you have deleted a service bus that is created in the subscription and trying to recreate it with the same name using the deployment.
Kindly note that the service bus namespace is unique across Azure and once you delete it, you would have to wait for 4 hours before recreating it with the same name. Please refer to the FAQ section for reference - Why am I not able to create a namespace after deleting it
Hope this answers your question. Please let us know if you still need any additional assistance or clarification around this.
