HTMX with Handlebars Client side template does not work with JSON Arrays

[tuaris]

I've tried this with HTMX 2.x and 1.x and the current version of Handlebars.

I have the follow data in this format:

{
  "items": [
    {
      "key1": "value1",
      "key2": "value2",
      "key3": {
        "subkey1": "value3",
        "subkey2": "value4"
      },
      "key4": "value4",
      "key5": "value5"
    },
    {
      "key1": "value1",
      "key2": "value2",
      "key3": {
        "subkey1": "value3",
        "subkey2": "value4"
      },
      "key4": "value4",
      "key5": "value5"
    },
    {
      "key1": "value1",
      "key2": "value2",
      "key3": {
        "subkey1": "value3",
        "subkey2": "value4"
      },
      "key4": "value4",
    },
    {
      "key1": "value1",
      "key2": "value2",
      "key3": {
        "subkey1": "value3",
        "subkey2": "value4"
      },
      "key4": "value4",
      "key5": "value5"
    }
  ]
}

The following HTMX does not print out a table with 4 rows. Instead it's a table with only one empty row:

		<div hx-ext="client-side-templates">
			<div hx-get="/path/to/data" 
				 hx-swap="innerHTML"
				 hx-target="#data_table"
				 hx-trigger="load, click, every 600s"
				 handlebars-array-template="data_template">
				<button class="btn btn-primary">Refresh Data</button>
			</div>
			
			<template id="data_template">
				<table class="table table-striped">
					<thead>
						<tr>
							<th>Address</th>
							<th>Client Hostname</th>
							<th>Hardware Type</th>
							<th>MAC Address</th>
						</tr>
					</thead>
					<tbody>
					
					{{#each items}}
					<tr>
						<td>{{key1}} </td>
                                                <td>{{key2}} </td>
                                                ...
					</tr>
					{{/with}}
					</tbody>
				</table>
			</template>		
			
			<div id="data_table"></div>	

If I only have {{items}}, like so:

...
<td>{{items}} </td>

I get this:

[object Object],[object Object],[object Object],[object Object]

Is this a bug or am I missing something?

I got it to work by changing the structure of the source data to match this example: https://github.com/bigskysoftware/htmx/issues/801#issuecomment-1893989978. Also seems like you can't template the full table, but instead need to do tbody only?
