Hello @Łukasz
Based on the error message you provided, it seems that the issue is related to the disk space on the server where you are trying to deploy your Java Azure Functions app. The error message indicates that there is not enough space on the disk.
However, you mentioned that you have a lot of free space on the storage account attached to your Azure Functions app. It's important to note that the storage account is used to store data and files, but it's not related to the disk space on the server where your app is deployed. To resolve the issue, you may need to check the disk space on the server where you are trying to deploy your app. You can do this by logging into the server and checking the available disk space.
If the disk space is low, you may need to free up some space by deleting unnecessary files or increasing the disk space. If you are not able to log into the server, you may need to contact your server administrator or hosting provider for assistance.
I hope this helps
