Fixes #86
I could reproduce the issue locally and noticed that the HTTP call made by the proxy to get the dashboard page from Grafana Cloud was hanging (the HTML was fetched and served, but the HTTP connection didn't close).
I noticed that we used the
write()function to send the response to the client, while the Express documentation mentions thesend()function. Using it seems to solve the issue.
