Trying to set the ID of a Request Type based on an incoming webhook

[Ste404]

Hi there,

I am passing the Request Type ID into JSM via a webhook.

I want to set that as part of the automation that is creating this issue but I am failing horribly.

In the Additional Fields I have this

{
"fields": {
"Affected services": [
{{#lookupObjects}}
{"id": "{{Service ID}}"}{{^last}},{{/}}
{{/}}
],
"Request Type": {
"id": "{{webhookdata.Request}}"
}
}
}

webhookdata.Request comes in as a number which matches a request type id.

What should I change here to make this work?

Thanks.
