AttributeError: 'Server' object has no attribute 'task'

See original GitHub issue

I am trying to run a asynchronous webserver using microdot libraries microdot.py and microdot_asyncio.py and came across the following error:

Traceback (most recent call last): File "<stdin>", line 40, in <module> File "uasyncio/core.py", line 1, in run File "uasyncio/core.py", line 1, in run_until_complete File "uasyncio/core.py", line 1, in run_until_complete File "<stdin>", line 37, in main File "microdot_asyncio.py", line 165, in start_server File "uasyncio/stream.py", line 1, in wait_closed AttributeError: 'Server' object has no attribute 'task'

Does it have to do with my asyncio version? I am running MicroPython v1.15 with the microdot files frozen into a custom build. Thanks!

@dpgeorge Sure. While I was debugging this yesterday I came up with a fix as well, so I have created a PR: https://github.com/micropython/micropython/pull/7365.

You can’t basically call server.wait_closed() too soon after calling create_server(). Sometimes you may get lucky and everything works, other times, wait_closed() tries to access attributes of the server object that haven’t been created yet.

That does sound like a bug in uasyncio, which should probably be fixed.
