JSONDecodeError when using client.query()

[xywei00]

Hi, I would like to run the example notebook of clip query in colab: https://github.com/rom1504/clip-retrieval/blob/main/notebook/clip-client-query-api.ipynb. However, when calling cat_results = client.query(text="an image of a cat"), I got the following error:

---------------------------------------------------------------------------

    975         except JSONDecodeError as e:

During handling of the above exception, another exception occurred:

Could you please provide some information on how this can be resolved? Also, it seems the ui is not working: https://rom1504.github.io/clip-retrieval/

Thank you in advance for your help!
