I am trying to create a login authentication page for a streamlit application using streamlit authenticator, after which the user will be taken to the main app if login is successful but I keep getting this error

@Taiwo_Osunrinde

with open('./login_credentials.yaml', 'w') as file:
    yaml.dump(config, file, default_flow_style=False)

Put that code at the bottom of the page.

@ferdy do you mean the bottom after the main application body. Thanks
