Hi, Iâm trying to hack something with Pharo 6.1 and Phillips Hue[1] (they have a simple REST API). When I try to do a GET request with Zinc like this: ZnClient new url: 'http://192.168.0.115:80/api/1028d66426293e821ecfd9ef1a0731df/lights/'; get I get a âConnectionClosed: Connection closed while waiting for dataâ exception. The service provides a JSON response that I can get without a problem by using a web browser or curl. Also if I try to access fewer data (e.g. adding /1 to the url, so it gets only one resource) I donât get the exception. What is even more strange, when I resume the exception I get the desired response i.e. this works: [ ZnClient new url: 'http://192.168.0.115:80/api/1028d66426293e821ecfd9ef1a0731df/lights/'; get ] on: ConnectionClosed do: [ :ex | ex resumeUnchecked: ex defaultResumeValue ] Of course I cannot share the server that is on my local network for resting, but maybe anyone knows it there are any known issues with Zinc, or if there are ways for me to debug the issue further.
