Local JSON data loading problem

[HaochenWang1243]

Hi. When I try to load local json data, the following error is reported ValueError: Unsupported source directory format for JSON.
I looked at the code and it seems this line

EasyTemporalPointProcess/easy_tpp/preprocess/data_loader.py

Line 74 in 1d2ce04

if source_dir.endswith('.json'):

requires the folder's name to end in .json...? This seems inconsistent with the example notebook for loading json data from huggingface
