Flow trigger issue

[Evonux]

Hi there, I’m trying to create a flow trigger with a custom schema (followed these docs).

The types are going through properly:

However, I never see the trigger actually do what it’s supposed to do, in this example, send an email without any variables.

I also tried using the admin API to trigger it, but I run into another issue:

My shopify.extension.toml file is:

[[extensions]]
name = "Lead form submission"
handle = "lead-form-submission"
type = "flow_trigger"
description = "Create an action that triggers when a lead form is submitted"
schema = "./schema.graphql"
return_type_ref = "Submission"

[settings]
  [[settings.fields]]
  type = "schema.Submission"
  key = "submission"

and my schema.graphql is:

type Submission {
	fields: [Field!]!
}

type Field {
	label: String!
	value: String!
}

Would love to know what the issue is…

Your payload is one giant string, but should be an object

Trigger reference

Yep, that worked…
Although to be fair GraphiQL did throw me off with the error:
