Undefined event for select element with hx-trigger=”change,load”

[helander]

HTML:
<select name="foobar" hx-post="/myurl" hx-trigger="change,load" hx-vals='js:{evtype: event.type}' >

Server response to post at /myurl
returns 200 and html fragment on change event
return 204 and empty on load event

Purpose: generate call to server URL on init as well as on changes (required by backend internals)

Result:
Page loads correctly and post to server url is issued as expected.
Once I change the select input I get the following error (probably in htmx:confirm stage)

TypeError: undefined is not an object (evaluating 'event.type') Error: {}

and no post takes place to the server.

Am I doing something wrong or is this potentially a bug.
