Javascript simple rule trigger warning

Setup, Configuration and Use Beginners

I have a item

Number:Illuminance  HueWoonkamerAmbientIlluminance          "Lichtsterkte"           <lamp2>               (BG_Woonkamer)   ["Measurement", "Light"] {channel="hue:0106:1d920141a4:20:illuminance", widgetOrder = "e"}

and a rule

rules.when().item('HueWoonkamerAmbientIlluminanc').changed().then(event => {
   console.log("Binnen trigger rule: " + HueWoonkamerAmbientIlluminanc.state );
}).build ("rule 17")

and get a warning I can’t explain reading the documentatiën

 Item 'HueWoonkamerAmbientIlluminanc' needed for rule 'rule-17-ca733f77-80fa-4618-a5c5-b98465d65795' is missing. Trigger 'baa3d813-0d02-494c-9e36-c9bb8d8a51ee' will not work.

What do I miss?

Typo, missing “e” in your rule.

Thanks.
Now I get the following error

[ERROR] [automation.script.file.javartrial.js] - Failed to execute rule rule-17-ce088287-10c3-4c89-9632-16f8b58975ad: ReferenceError: "HueWoonkamerAmbientIlluminance" is not defined: ReferenceError: "HueWoonkamerAmbientIlluminance" is not defined

Shouldn’t widgetOrder not be an integer instead of a letter?

I’m both cases the error means you are referencing an Item that doesn’t exist. That usually means a typo in the Item name as you’ve typed it in the rule.

Check the spelling and remember case matters.

I copied the item from the items file.
I’m 100% sure that item exist.
The DSL rule as below is working

rule "Woonkamer lampen uit als het licht wordt" 
when
    Item HueWoonkamerAmbientIlluminance changed 
then
    logInfo("default.rules", "Lichtsterkte woonkamer veranderd: " + HueWoonkamerAmbientIlluminance.state )
end
