Get_list_database() does not work when working with influxDB in Python

I’m currently working on influxdb in Python.
When client.get_list_measurements () is executed, an error occurs and the list cannot be acquired.

I think the command is correct in the documentation, but why?
https://influxdb-python.readthedocs.io/en/latest/api-documentation.html?
highlight=get_list_measurements#influxdb.InfluxDBClient.get_list_measurements

In addition, client.get_list_database() works fine and you can get the database list.
