Object reference not set to an instance of an object

I don't seem to be able to get the data formatted correctly as an object. Looks like an object but isn't

    <Scenario Id="ReportCall" Type="REST">

Well I found the cause of this error. [[CallStartTimeUTC].ToString("yyyy-MM-ddTHH:mm:ssZ")]


How can I fix it?

This is from https://www.3cx.com/docs/server-side-crm-template-xml-description/

These are the lines causing the error:

<Value Key="CallStartTimeUTC" Passes="0" Type="String">[CallStartTimeUTC].ToString("yyyy-MM-ddTHH:mm:ssZ")</Value>
<Value Key="CallEndTimeUTC" Passes="0" Type="String">[CallEndTimeUTC].ToString("yyyy-MM-ddTHH:mm:ssZ")</Value>

And this is how you fix this:

<Value Key="CallStartTimeUTC" Passes="0" Type="String">[[CallStartTimeUTC].ToString("yyyy-MM-ddTHH:mm:ssZ")]</Value>
<Value Key="CallEndTimeUTC" Passes="0" Type="String">[[CallEndTimeUTC].ToString("yyyy-MM-ddTHH:mm:ssZ")]</Value>
