OSError: stream operation not supported

[tongclement]

HI again!

Unfortunately, I encountered some issues and I believe it has something to do with decoding the Json from GitHub. Here is the full trace. Again, I will try to debug this on my end. It is quite likely that I set it up wrong. But any help will be appreciated. Thanks.

This might be too late for you, but I stumbled across this issue before solving it myself:
You may simply not call .json() of the Response object more than once.
Solution: Get rid of the line print(file_list.json()). If you really want to print, save the result of file_list.json() in a variable.
Cheers

Wow many thanks for sharing!
I may reconsider micropython again for future projects once OTA works.
