resend not working in internalMutation

I had a problem where I wasn't able to send emails with Resend. My API key was configured, my resend domain was verified and magic link email were working fine (after setting the from param). But when I tried to send emails at runtime resend.emails.send() would give the error

{
  name: 'application_error',
  message: 'Unable to fetch data. The request could not be resolved.'
}

{
  name: 'application_error',
  message: 'Unable to fetch data. The request could not be resolved.'
}

After a long time debugging I found out that my problem was that I was trying to send emails from an internalMutation. I switched to internalAction and all immediately worked. Could someone please explain the reason for this?
I also read the docs extensively but I hadn't found or anticipated that this would happen
