XSOAR CreateEmailHtmlBody Error

[CodyReavis]

I am attempting to create an email from an HTML template but am receiving an error stating "Item not found (8) on list..." followed my the HTML contents of my saved list. I am sure it is looking for the key attribute that is required for the script, however I am not sure what it is asking for. 

Based on docs, the key argument is the "The context key to store the HTML body". I did some searches but am still confused on what it is needing to successfully execute.

@CodyReavis Is it possible that the HTML template has a context key variable in ${} notation and the key is not present in the context? Please upload some screenshots if possible.

Thanks,

Absolutely, so here is the variables set

The listTemplate is taken directly from XSOAR while the incident.details is taken from and ID I set in the HTML.

Here is the output of the error:

To me, that is signifying that it cannot find the key, but I am still unsure what that context key is based on the docs I have read here:

I see the problem. The list template should be the name of the list only and not part of the ${} notation. for ex. !CreateEmailHTMLBody listTemplate=DefenseStormAlertTemplate ...
