I run emoncms and NodeRed on an Amazon Web Services Ubuntu server. I created a flow that goes to a Gmail account, gets an email from my water utility company with my water usage, extracts the gallon value, and forwards the result to emoncms. It works when I deploy it, but the next day when it collects the next daily usage email, NodeRed becomes unresponsive. It disconnects me if I am logged in, and gives a “this site can’t be reached” error when I try to navigate to the admin page. I’m pasting in the function and the error below hoping someone can help me.
Function:
try {
var startpos = msg.html.search(“usage of “)+8;
var endpos = msg.html.search(” G exceeded”);
var gal = { payload: msg.html.substring(startpos,endpos) };
return [msg, gal]
} catch(e) {
node.error(“hit an error”, e);
}
Error:
