Invites not sent.

[Lebannen74]

Hello,

Thanks for Splitpro, it's really great. :)

I have a problem with invites.
I create a new expense, type the email in the field then "Send invite to user". I also try with "Add to Split Pro".
In both case, the invite is never received.
The email is a test email linked to one of my gmail account. for example "user+testx@gmail" where x is a number I change each test.
There is no errors in the log.

If I use the same email on the signin page, I receive the magic link without problem so the smtp settings are likely correct.

any idea how to solve this problem ?

extract of my .env file

NEXTAUTH_SECRET="secret"
NEXTAUTH_URL="https://splitpro.example.com"
DEFAULT_HOMEPAGE="/balances"
NEXTAUTH_URL_INTERNAL="http://localhost:3300"

ENABLE_SENDING_INVITES=true
DISABLE_EMAIL_SIGNUP=false

FROM_EMAIL="user@gmail.com"
EMAIL_SERVER_HOST="smtp.gmail.com"
EMAIL_SERVER_PORT="587"
EMAIL_SERVER_USER="user@gmail.com"
EMAIL_SERVER_PASSWORD="password"
EMAIL_TLS_REJECT_UNAUTHORIZED=1

Your SMTP and env settings are fine. This is a bug in the Add Expense screen: the "Send invite to user" button never asks the server to send an email.

In SelectUserOrGroup.tsx, both buttons use the same handler, and it always passes false:

const handleAddEmailClickFalse = useCallback(() => onAddEmailClick(false), [onAddEmailClick]);
// ...
<Button ... onClick={handleAddEmailClickFalse}>   // "Send invite" (should be true)
<Button ... onClick={handleAddEmailClickFalse}>   // "Add to Split Pro" (false is correct)

split-pro/src/components/AddExpense/SelectUserOrGroup.tsx

Line 108 in fd089df

const handleAddEmailClickFalse = useCallback(() => onAddEmailClick(false), [onAddEmailClick]);

split-pro/src/components/AddExpense/SelectUserOrGroup.tsx

Lines 147 to 165 in fd089df

	{enableSendingInvites && (
	<Button
	className="mt-4 text-cyan-500 hover:text-cyan-500"
	variant="outline"
	disabled={!isEmail.success}
	onClick={handleAddEmailClickFalse}
	>
	<SendIcon className="mr-2 h-4 w-4" />
	{t('expense_details.add_expense_details.select_user_or_group.send_invite')}
	</Button>
	)}
	<Button
	className="mt-4 text-cyan-500 hover:text-cyan-500"
	variant="outline"
	disabled={!isEmail.success}
	onClick={handleAddEmailClickFalse}
	>
	<UserPlusIcon className="mr-2 h-4 w-4" />
	{t('expense_details.add_expense_details.select_user_or_group.add_to_split_pro')}

That means inviteFriend is called with sendInviteEmail: false, so sendInviteEmail() is never reached and nothing is logged, which matches what you see:

split-pro/src/server/api/routers/user.ts

Lines 78 to 82 in fd089df

	if (input.sendInviteEmail) {
	sendInviteEmail(input.email, session.user.name ?? session.user.email ?? '').catch((err) => {
	console.error('Error sending invite email', err);
	});
	}

Magic links work because they go through a different path (sendSignUpEmail). The invite button in the group "add members" dialog also works, because it correctly calls onAddEmailClick(true).

The fix is to add a handleAddEmailClickTrue = useCallback(() => onAddEmailClick(true), [onAddEmailClick]) and use it on the "Send invite" button. Until that is merged, the workaround is to add the person to a group via the group's "add members" dialog and use the invite button there. This is also tracked in #697.

One more thing to know: if the email already belongs to an existing user (for example you already signed in with that address), inviteFriend returns that user and skips the invite entirely, so no email is sent in that case either.
