@ma-za-kpe I implemented your sample accessing the JSON file... it's working for me.
You can see the code in the links below...

Thank you for this...let me give it a go.

FYI: I was able to reproduce your issue when I tried to update my project to the latest version of compose and accompanist (1.2.0-alpha08 and 0.24.7-alpha respectively)
Check here: google/accompanist#1140
I reverted this change and it worked.
