Azure DevOps release deployment failing Disk Space Error

I have an app I am trying to deploy through azure's DevOps pipeline. I have successfully deployed apps before, and the first build of this app deployed fine. However all subsequent builds have been failing at the deployment step. They seem to be specifically failing at the "Deploy Azure App Service" step, generating a ERROR_NOT_ENOUGH_DISK_SPACE error code.

The deployment terminal output shows the following errors:

The first error seems to be caused by the remote server failing to add a git object. This error will usually occur 2-3 times each deployment, and will result in the "Retrying to to deploy the package" message shown.

The second error will happen once and will end the deployment. I have been to the link the error recommends and there is no help section for this type of error. I downloaded the build file and it is only 49.3 MB large, and the Microsoft servers have a 10GB size for deployments. I am running on a hosted build agent, not a private one.

Other questions I found online similar to this are mostly unanswered. Some have been updated later to say the deployment started working for seemingly no reason.

Any help would be appreciated.

For anyone else who gets the same problem, I basically had too many other apps taking up space on my azure account. The article Brendan Green linked explains this. (https://blogs.msdn.microsoft.com/puneetgupta/2017/06/06/azure-app-service-what-is-taking-my-disk-space-for-my-azure-web-app/)

By going to the Quotas page on any of your azure apps (in the azure portal) you can see how much space you have left.
