Error: Cannot convert a Symbol value to a string

Question

I'm having issues with TypeError in the Next.js API routes folder. I'm receiving the same error over and over again "Cannot convert a Symbol value to a string", but there are no types that have Symbol, nor would it be converted to a string. The only thing I can think of is the error message shown below, but I've tried fixing that and still no luck. Below is /api/email/meetingNotification and is called in a POST using the Fetch API:

/api/email/meetingNotification

import { NextResponse } from 'next/server';
import MeetingNotification from "../../../../../emails/meetingNotification";
import { resend } from '@/utils/resend';

interface EmailData {
    schoolName: string;
    email: string;
    clubName: string;
    meetingDate: string;
    meetingTime: string;
    meetingDescription: string;
    meetingName: string;
    location: string;
    type: string;
    mandatory: boolean;
    meetingId: string;
    clubCode: string;
}

export async function POST(request: Request) {
    const emails: EmailData[] = await request.json();

    try {
        const emailPromises = emails.map(({
         schoolName,
         email,
         clubName,
         meetingDate,
         meetingTime,
         meetingDescription,
         meetingName,
         location,
         type,
         mandatory,
         meetingId,
         clubCode
         }: EmailData) => {
            return resend.emails.send({
                from: `${clubName} <${clubCode}@clubcentric.org>`,
                to: email,
                subject: `A new meeting has been scheduled for ${clubName}`,
                react: MeetingNotification({
                    schoolName,
                    location,
                    type,
                    clubName,
                    meetingDate: new Date(meetingDate).toDateString(),
                    meetingId,
                    meetingTime,
                    meetingDescription,
                    meetingName,
                    mandatory,
                })
            });
        });

        await Promise.all(emailPromises);

        return NextResponse.json({ status: 'Ok' }, { status: 200 });
    } catch (e: unknown) {
        console.error('Failed to send emails:', e);
        return NextResponse.json(
            { error: 'Internal server error. Please try resending the emails.' },
            { status: 500 }
        );
    }
}

sendMeetingNotification();

        if (meetingData.meeting_data.push_notification) {
            const { data: membershipsData, error: membershipsError } = await supabase
                .from('memberships')
                .select('user_id')
                .eq('club_id', userId);

            if (membershipsError) {
                console.error('Error fetching memberships:', membershipsError.message);
                toast.error("There was an error: Memberships Unavailable")
                return;
            }

            const emails = [];

            for (const member of membershipsData) {
                const { data: userDirectoryData, error: userDirectoryError } = await supabase
                    .from('user_directory')
                    .select('email')
                    .eq('user_id', member.user_id);

                if (userDirectoryError) {
                    console.error('Error fetching user directory:', userDirectoryError.message);
                    toast.error("There was an error: User Directory Unavailable")
                    continue;
                }

                for (const members of userDirectoryData) {
                    emails.push({
                        schoolName: clubSchool,
                        email: members.email,
                        clubName: clubName,
                        meetingDate: selectedDate?.toISOString(), 
                        meetingTime: `${startTime} - ${endTime}`,
                        meetingDescription: meetingData.meeting_data.description,
                        meetingName: meetingData.meeting_data.title,
                        mandatory: meetingData.meeting_data.mandatory,
                        clubCode: clubCode,
                        location: meetingData.meeting_data.location,
                        type: selectedType,
                        meetingId: meetingData.meeting_id,
                    });
                }
            }

            // Send POST request to the endpoint
            const response = await fetch('/api/email/meetingNotification', {
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json',
                },
                body: JSON.stringify(emails),
            });

            if (!response.ok) {
                console.error('Failed to send emails:');
                toast.error("Notification System Error!")
            } else {
                console.log('Emails sent successfully');
                router.push("/dashboard/club/meetings")
            }
        } else {
            console.log('Push notifications are disabled: Emails not sent!');
        }
    }

Any help would be appreciated!

I've tried asking Claude and other AI to find a solution, they haven't been able to. Additionally, I've searched everywhere for any Symbol types, but there are none. This is the error message:
