"VIEW TASK" banner in the email notification has broken link

I’m on 0.24.2

When I receive an email notification, the “VIEW TASK” banner contains a broken link, here is the pure html code I can see:

	<p style=3D"color: #9CA3AF;font-size:12px;border-top: 1px solid #dbdbdb;ma=
rgin-top:20px;padding-top:20px;">
		If the button above doesn't work, copy the url below and paste it in your=
 browser's address bar:<br/>
		tasks/3571
	</p>

Previously it was:

	<p style=3D"color: #9CA3AF;font-size:12px;border-top: 1px solid #dbdbdb;ma=
rgin-top:20px;padding-top:20px;">
		If the button above doesn't work, copy the url below and paste it in your=
 browser's address bar:<br/>
		https://VIKUNJA_URL/tasks/3449
	</p>

It seems that https://VIKUNJA_URL/ is missing.
Latest working release for me was at least 0.21.0

Did you set the publicurl?

I still had frontendurl
Sorry for asking the obvious
