[SOLVED] Functions: Cannot read properties of undefined (reading 'json')

 
module.exports = async function (req, res) {
    const client = new sdk.Client();
    const database = new sdk.Databases(client);
 
    const databaseId = "id";
    const notificationsCollectionId = "id";
 
    client
        .setEndpoint(req.variables.APPWRITE_FUNCTION_API_ENDPOINT)
        .setProject(req.variables.APPWRITE_FUNCTION_PROJECT_ID)
        .setKey(req.variables.APPWRITE_FUNCTION_API_KEY);
 
    try {
        const payload = JSON.parse(req.payload);
        const mentionedUsers = payload.mentions || [];
        const message = payload.message || "You were mentioned in a post";
 
        for (const userId of mentionedUsers) {
            await database.createDocument(databaseId, notificationsCollectionId, sdk.ID.unique(), {
                userId: userId,
                message: message,
                read: false,
                createdAt: new Date().toISOString(),
            });
        }
 
        res.json({ success: true, message: "Notifications created successfully." });
    } catch (error) {
        res.json({ success: false, message: error.message });
    }
};```

const payload = req.bodyJson;
const mentionedUsers = payload['mentions'] || [];

const payload = req.bodyJson;
log(payload);
const mentionedUsers = payload['mentions'] || [];
