The 403 error in this scenario typically signifies that the user attempting to deploy Drupal 10 on Azure's app service does not have sufficient permissions to access or deploy to the desired location. This could be due to a number of factors, including incorrect login credentials, insufficient Azure permissions, or permission limitations for the specific app service resource. Resolving the issue will typically involve correcting the root cause of the permission issue, which may involve adjusting permission settings or contacting Azure support for assistance.
