Hi @Marin Binzari ,

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

The error message "There is not enough space on the disk" indicates that the disk space allocated for your Azure Function App is inadequate. This situation can arise when the application consumes all available disk space, especially in the temporary storage utilized by the Azure environment.

• Check the disk usage of your Function App to identify what is using up space. You can use the Azure Portal to track the storage metrics. If there are any unnecessary files or logs, delete them to free up space.
• If your application needs additional storage, consider setting up local storage resources to handle temporary files more efficiently.
• For data that needs to be retained, utilize external storage solutions such as Azure Blob Storage or Azure SQL Database instead of depending on the local disk.

If the problem continues after following these steps, you may need to upgrade your App Service plan to a higher SKU that offers additional resources.

For your reference, please review the following documentations for further clarification:

• No space is available on drive E or F
• Resolve issues when creating, deleting, or restoring Azure function apps

I hope this helps! Let me know if you have any further questions or need additional assistance.
