htmx: hx-swap='outerHtml' gets ignored

Question

This button should replace a <tr> but somehow "hx-swap" does replace the inner HTML, not the outer HTML:

<button hx-get="{url}" hx-target="#offer_{id}" hx-swap="outerHtml" 
        class="btn btn-secondary btn-sm">Edit</button>

See: hx-swap

Answer 1

The string is case-sensitive. it works if you write outerHTML instead of "outerHtml".
