you can use your a dummy email account, and check your console - copy/paste in your browser the url - that is all.

I dont understand what you mean by this? I used a dummy email: dummy@example.com and still it shows error "Error sending email - try again?"

Fixed by adding
NEXT_PRIVATE_VERIFICATION_SECRET=""
The secret can be generated using
openssl rand -hex 32
