Uncaught Exception in openhab-v2.js:261:37
Closed this issue · 2 comments
When openhab responses status with 503 no body will be send, so the following code will fail.
var body = JSON.parse(response.body);
The response object looks like this:
{"statusCode":503,"body":"<html>\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html;charset=utf-8\"/>\n<title>Error 503 Jersey is not ready yet!</title>\n</head>\n<body><h2>HTTP ERROR 503</h2>\n<p>Problem accessing /rest/items/Mower_Activated. Reason:\n<pre> Jersey is not ready yet!</pre></p><hr><a href=\"http://eclipse.org/jetty\">Powered by Jetty:// 9.4.11.v20180605</a><hr/>\n\n</body>\n</html>\n","headers":{"connection":"close","cache-control":"must-revalidate,no-cache,no-store","content-type":"text/html;charset=iso-8859-1","content-length":"373","server":"Jetty(9.4.11.v20180605)"},"request":{"uri":{"protocol":"http:","slashes":true,"auth":"user:pass","host":"localhost:8080","port":"8080","hostname":"localhost","hash":null,"search":null,"query":null,"pathname":"/rest/items/itemname/state","path":"/rest/items/itemname/state","href":"http://user:pass@localhost:8080/rest/items/itemname/state"},"method":"PUT","headers":{"authorization":"Basic blablablablabla=","content-length":19}}}

I can't even start node-red anymore because of this (similar) exception.

I changed ".node-red/node_modules/node-red-contrib-openhab-v2/openhab-v2.js:262:23" from "210" to "400", because response.body contained " .... HTTP/400 ...".
Node-Red starts again, workflows are looking fine. I'm sure this is just a dirty hack, but at least all the flows are up and running again.
