Problem with "hello AIRA"

I’m reading the article “Basic usage of AIRA” on robonomics wiki.
I’ve download special version of AIRA for winter school 2021, from here and I’m running command:

$ rosrun hello_aira hello_aira

and then go to Dapp. But all, that i see, is a loading page:

Also, I’ve tried the latest stable realize AIRA: AIRA 1.1 LTS and I have the same result.

I’ve found the answer. In an other article Interact with AIRA you can download and install newer version of “hello aira” package. Everything works after installation.

This problem will be fixed in future releases.
