The system failed to generate presentation outlines due to invalid or empty JSON input. The error originates from dirtyjson when attempting to parse the outline data, resulting in Expecting value: line 1 column 1 (char 0). This typically occurs when the input string is empty or improperly formatted. Please verify the data source and try again.
I used gemma3.27it Local.
