Error when checking 'Using Expressions' challenge
I realise this question has been asked a few times already but couldn't find any suggested solution that worked for me, so here goes.....
I am currently trying to complete the 'Using Expressions' challenge on the Trailhead Lightning site, and keep getting the same error.
Code
Component
<aura:component >
<aura:attribute name="IsSunday" type="Boolean" default="false"/>
<aura:attribute name="IsMonday" type="Boolean" default="false"/>
<aura:attribute name="IsTuesday" type="Boolean" default="false"/>
<aura:attribute name="IsWednesday" type="Boolean" default="false"/>
<aura:attribute name="IsThursday" type="Boolean" default="false"/>
<aura:attribute name="IsFriday" type="Boolean" default="false"/>
<aura:attribute name="IsSaturday" type="Boolean" default="false"/>
<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
<aura:if isTrue="{!v.IsSunday}">
<p>Today is Sunday</p>
</aura:if>
<aura:if isTrue="{!v.IsMonday}">
<p>Today is Monday</p>
</aura:if>
<aura:if isTrue="{!v.IsTuesday}">
<p>Today is Tuesday</p>
</aura:if>
<aura:if isTrue="{!v.IsWednesday}">
<p>Today is Wednesday</p>
</aura:if>
<aura:if isTrue="{!v.IsThursday}">
<p>Today is Thursday</p>
</aura:if>
<aura:if isTrue="{!v.IsFriday}">
<p>Today is Friday</p>
</aura:if>
<aura:if isTrue="{!v.IsSaturday}">
<p>Today is Saturday</p>
</aura:if>
</aura:component>
CONTROLLER
({
doInit : function(component) {
var theDate = new Date();
if (theDate.getDay()==0) {component.set("v.IsSunday", true);}
if (theDate.getDay()==1) {component.set("v.IsMonday", true);}
if (theDate.getDay()==2) {component.set("v.IsTuesday", true);}

if (theDate.getDay()==4) {component.set("v.IsThursday", true);}

if (theDate.getDay()==6) {component.set("v.IsSaturday", true);}
}
})

There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org.

I tried creating a new Developer edition, as per a suggestion on another thread, but got the same error (albeit with a different error id).
I went back to my original developer edition and tried another suggestion - modifying the code in my component to have only one <aura:if> statement and one <aura:set attribute....> tag, as shown below:

<aura:if isTrue="{!v.IsSaturday}">

Same end result:

Something like simple should do it. The controller is not even needed
Thx
The key is to use an expression.
For what it's worth, the error message turned out to be something of a red herring. I thought that there was some kind of issue with my environment. In fact, what actually ended up fixing it was simply changing all my attribute/variable names to those specified in the challenge. For example, instead of using 'v.IsSunday', 'v.IsMonday' etc....I used v.DayOfTheWeek and set it to "Sunday", or "Monday" etc...
Similarly, in the component, I changed the test from <aura:if isTrue="{!v.IsSunday}">.....to <aura:if isTrue="{!v.DayOfTheWeek=='Sunday'}">
Hope this helps anyone else who has run into the same issue.
thx
