I’ve configured my app to only use Passwordless connection, but OTP / verification code emails are no longer sending with a custom email provider. They were previously working with the test provider, but after switching to using Azure Communication Services the emails aren’t sending anymore.
When I try to login, I get two logs:
1: Successful “Code/Link Sent” log
2: “Failed Sending Notification” log with the error:
“Error sending email: Request body validation error. See property ‘senderAddress’”
The “Send Test Email” button in the Branding → Email Provider section successfully sends an email, but whenever I try to log in or send a test email from Authentication → Psaswordless section, it fails to send.
