Hey, thx for your PR.. Unfortunately if you look at the tests, they failed to fetch the wether stat. I don't know why they did not fail, will open an issue an look into it..

Hi @iinsertNameHere, I figured out why the tests were failing. The test config location was "San Francisco", and the space was breaking the wttr.in url. I added a replace(" ", "+") as instructed by wttr.in and it is working now. As for the tests, I noticed that they were passing for me locally because the weather info was cached, so I added a -n to each test script to force a refresh. I'm still not sure why it was passing in the github workflow though, so you might need to further look into that.
