Error Configuring HACS on Container version of HA -"Report to integration author"

My (new 6 May 2024) Configuration is raspberry pi 5 64 bit debian 6.6.20 install with Docker installed as the Container
Docker used to install HomeAssistant
Followed instructions in hacs.xyz/docs/user
Selected the ‘Container’ tab in hacs.xyz/docs/setup/download and follow instructions with no errors
Rebooted the raspberry pi and relogged in to HA
Followed configuration instructions in hacs.xyz/docs/configuration/basic
Successfully authorized hacs after github log in
— but back in HA, the Device Registration never gives a ‘Submit’ button and the spinning wheel indicator waits forever.
The error in the log reads:
"
2024-05-06 19:04:20.064 WARNING (MainThread) [homeassistant.data_entry_flow] custom_components.hacs.config_flow::HacsFlowHandler calls async_show_progress without passing a progress task, this is not valid and will break in Home Assistant Core 2024.8. Please report it to the custom integration author
"
Is this something I can fix on my system or is this an integration/installation workflow error?
