st.container horizontal parameter errors despite the python code working perfectly

[1TSnakers]

Doing:

cont = st.container(horizontal=True)

makes an error:

TypeError: LayoutsMixin.container() got an unexpected keyword argument 'horizontal'
Traceback:
File "streamlit/runtime/scriptrunner/exec_code.py", line 123, in exec_func_with_error_handling

                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Despite the python code working perfectly.
