NameError: name 'ujson' is not defined

I listed the files from S3 urls = ['s3://' + f for f in fs.glob("s3://noaa-goes16/ABI-L2-ACMC/2022/116/*/*.nc")] given around len(urls) 272 files and then generated the jsons files and created in the ./jsons/ directory, however, I run into an issue with gen_json() function NameError: name 'ujson' is not defined. I followed @lsterzinger tutorial in

there’s still a typo:

m_list = []
for js in tqdm(json_list):
    with open(js) as f:
        m_list.append(fsspec.get_mapper("reference://", 
            fo=json.load(f), remote_protocol="s3",
            remote_options={"anon": True}))

json.load → ujson.load

Thanks for catching this typo @najiya-12 - I corrected the import to import ujson at the beginning of the tutorial. As @martindurant said, it should be installed alongside Kerchunk since it’s listed in the dependencies
