Hi @Gilg , Based on the given information, it seems that the error you are experiencing is related to notebook autosaving.
The error message "Failed to save revision: Notebook size exceeds limit" indicates that the notebook size is too large to be autosaved.
To resolve this issue, you can try the following solutions:
1. Manually save the notebook: Instead of relying on autosave, you can manually save the notebook by clicking on the "Save" button in the notebook toolbar. This will allow you to save the notebook even if it exceeds the autosave size limit.
2. Reduce the size of the notebook: If your notebook contains cells with large results, such as images generated by graphing tools like plotly and matplotlib, you can hide these large results to reduce the notebook size. This can be done by collapsing or deleting the cells that contain the large results.
