The website crashes when I do .length while writing a custom email template
Hey,
I was using Novu's digest feature to send emails. I can do
step.events.length
which gives me the total number of events.
Then I group the events using groupBy as described in this doc https://docs.novu.co/content-creation-design/handlebars-helpers
But when I use groupBy, it gives me an items variable. This seems to be a type Object instead of an array. So I'm unable to find the length of this item variable.
Also, the whole website crashes if I do items.length

It appears that using
items.length within the groupBy helper is causing issues because items is indeed an object and not an array. According to the documentation, the groupBy helper groups items based on a property, but it does not directly provide a length property for these grouped items (1) .
Instead, you should iterate through items and count the elements within each group. Here is a modified version of your template using an inline counter to determine the length of each group:
: Handlebars & Helpers
This workaround creates an inline variable length to store the length of each group.This is the error message I get when I did the above solution
{
"error": "Missing helper: "let""
}
Okay the solution was to use
{{#with items as |itemsArray|}}
{{itemsArray.length}} {{pluralize itemsArray.length "message" "messages"}}
{{/with}}
