Parsing an HTTP Response Groovy Errors in Hubitat

Ryan780 · 2018-10-18 15:30:26 UTC

I have a piston that works fine in ST but is completely non-functional in Hubitat and I can’t figure out why. Anyone else have any ideas?

These are the errors I’m getting in Hubitat

I don’t have a Hubitat, but your IF statement on line 27 above is totally blank…

Ryan780 · 2018-10-18 20:32:26 UTC

Yes…that’s because this piston is called from another and isn’t triggered on it’s own. It works fine in ST. Rather than have 5 copies of this statement in every piston that I use it for, which is like 10, I have one of these per LED strip. And I call to execute this piston from another. That wasn’t my question.

My question was about the groovy language error I recieved.

WCmore · 2018-10-18 20:37:15 UTC

I do this all the time, and that top IF is not needed for this.
(To be honest, I think it is asking for problems)

Ryan780 · 2018-10-18 20:42:21 UTC

There, I removed the if and got the same error. Can you answer MY question now rather than argue semantics?

Ryan780 · 2018-10-18 20:43:26 UTC

This is what is shown in the logs:

LOL, I wasn’t arguing…

When troubleshooting, I always look at the obvious first, and that IF was glaring at me. I would be doing you an injustice to not mention it. You are too quick to get defensive, when all I was trying to do was help.

I will let someone else tackle this

eibyer · 2018-10-18 20:59:33 UTC

Try breaking it down to the simplest GET and log $response and see if you actually are getting a $response.

Ryan780 · 2018-10-18 21:03:38 UTC

This is the piston:

And I get the same error:

I can request the same url in Chrome and I get the correct response back.

eibyer · 2018-10-18 21:31:16 UTC

I’m just getting started with HE myself and have not created any pistons there. Do you have any pistons in HE that makes webcalls that logs $responses that work?

Ryan780 · 2018-10-18 21:52:03 UTC

No, these are the first one’s I’ve tried that with.

eibyer · 2018-10-18 22:06:43 UTC

You’d probably have to tag the folks that ported wc to hubitat… I can’t remember his handle at the moment

Ryan780 · 2018-10-18 23:02:06 UTC

hey @jp0550 and @ajayjohn …any ideas?

Ryan780 · 2018-10-21 05:29:56 UTC

Guess this isn’t working for anyone. I’ll leave it in ST. VERY regretting this Hubitat purchase.

jrfarrar · 2018-10-29 21:12:52 UTC

I’m having issues with issuing a get request to an internal server also. Anyone successfully able to do this?

So OLD ST way…do not use “http://” in front of IP address…HE…needs to have “http://” in front of URL.

Ryan780 · 2018-10-29 21:31:43 UTC

Yeah, I am. That doesn’t help. You can see in the screencap above.
