We seem to be seeing this error frequently lately. Previously the fix was related to manually schedule tasks. This particular issue we ended up using the Save For Sharing fix to resolve the issue. We therefore are not sure of the specific issue, only that it was probably related to some sort of corruption.
Save for Sharing procedure
- While connected to Project Online Open the project in MS Project
- Navigate File > Share > Save For Sharing > Save As
- Save to local hard drive
- Exit MS Project
- Launch MS Project
- Open the project you just saved locally
- Navigate File > Save As > Save (Make sure your PWA instance is selected)'
- The Save To dialog should show your original project name as Read-only
- Click Save
- Republish
