RuntimeError: generator raised StopIteration

[ChrisH861]

I am trying to get data form the MetOffice API, I have adapted the forecastTokenizeLive example and I know my URL and GET headers are correct and should return data as the work when using the urequests library. However when using medea I get the below error before any data is returned.

line 104, in tokenizeValue 
    byte = gen.send(repeat) \
RuntimeError: generator raised StopIteration

The only thing I can think of is, I have noticed that the MetOffice API doesn't return content-length as part of its header. Am I correct in thinking this a requirement and is there any way of getting it working?

I had the same issue, and eventually solved it by changing the ssl.wrap_socket call in generateResponseBytes to

s = ssl.wrap_socket(s, server_hostname=host)

The try/except block that surrounds this line hides the true error and raises a StopIteration instead. In my case, further examination showed my true error to be OSError: (-30592, 'MBEDTLS_ERR_SSL_FATAL_ALERT_MESSAGE'), which eventually led me to this GitHub answer where this solution of adding server_hostname=host was proposed.
