no method or property "morgoth" on *pipeline.WindowNode?

[PrincipalsOffice]

I tried to use the provided TICK script from the README and I kept seeing that error when I ran kapacitor define cpu_alert -type stream -dbrp telegraf.default -tick cpu_alert.tick, what might have went wrong?

[nathanielc]

@PrincipalsOffice Sounds like the UDF configuration is not correct. Can you share your [[udf]] config section?

I installed kapacitor from HomeBrew in macOS Sierra.

[nathanielc]

Hmm, that looks right. And you say you are using the TICKscript from the readme?

[PrincipalsOffice]

Yea, I am not sure why, perhaps some kind of versioning issue? Removing the @morgoth() block would work though.

[aidanboran]

I had a similar issue last week -exactly the same error trying to save a tickscript.

for me, the problem was file permissions - I was running 'kapacitord' as user that didn't have correct/enough permissions.

I am running on an "arm" embedded device so have a weird setup....

I tried using the TICKscript from http://docs.morgoth.io/docs/getting-started/
Getting the same error:
"*invalid TICKscript: line 43 char 4: no method or property "morgoth" on pipeline.WindowNode"
