This error is related to the Microsoft SQL Server (MSSQL) source connector in Airbyte. The issue occurs when the SQL Server's tempdb database runs out of space during a sync operation. Let me explain the problem and provide some potential solutions based on the available information. The error message indicates that the SQL Server cannot allocate space for a temporary object in the tempdb database because the 'PRIMARY' filegroup is full. This can happen when dealing with large datasets or complex queries that require significant temporary storage. To resolve this issue, you have a few options: 1. Increase tempdb size: You need to allocate more space to the tempdb database on your SQL Server. This can be done by adding more files to the tempdb or increasing the size of existing files. 2. Optimize queries: If possible, try to optimize your queries or reduce the amount of data being processed at once. This might involve breaking down large syncs into smaller batches. 3. Clean up tempdb: Ensure that there are no unnecessary objects or long-running transactions holding space in tempdb. 4. Check for disk space: Make sure the disk where tempdb is located has enough free space. Unfortunately, the provided knowledge sources don't contain specific instructions for resolving this particular error in Airbyte. However, this is a SQL Server-specific issue that needs to be addressed on the database side. If you're using Airbyte Cloud, you may want to contact their support team for further assistance. If you're self-hosting Airbyte, you'll need to work with your database administrator to resolve the tempdb space issue on your SQL Server instance. For more general information about Airbyte's MSSQL source connector and potential issues, you can refer to the [Airbyte documentation](
