How to pass data from middleware to findContent

[vill3m647]

So I have a ConversationsMiddleware for user auth but now I need to use the user data as a input in the findNearestNeighborsOptions filter. Cant figure out a way to do this, can someone help?

Here is minimal code example:

const authenticateUser: ConversationsMiddleware = async (req: Request, res: Response, next: NextFunction) => {
    try {
        const token = ''
        let user
        try {
            user = await verify(token)
        } catch (err) {
            return res.status(401).json({
                error: err,
            })
        }

        res.locals.user = user

        next()
    } catch (err) {
        return next(err)
    }
}

const findContent = () => {
    return makeDefaultFindContent({
        embedder,
        store: embeddedContentStore,
        findNearestNeighborsOptions: {
            k: 5,
            path: 'embedding',
            indexName: VECTOR_SEARCH_INDEX_NAME,
            minScore: 0.6,
            filter: {} // need to use user data here
        },
    })
}

const generateUserPrompt: GenerateUserPromptFunc = makeRagGenerateUserPrompt({
    findContent: findContent,
    makeUserMessage,
    maxChunkContextTokens: 4000,
})

const conversationsRouterConfig: ConversationsRouterParams = {
    filterPreviousMessages: filter10PreviousMessages,
    llm,
    conversations,
    generateUserPrompt,
    systemPrompt,
    createConversationCustomData: customDataTest,
    maxUserMessagesInConversation: 100,
    middleware: [requireRequestOrigin(), requireValidIpAddress(), authenticateUser]
}

const config: AppConfig = {
    conversationsRouterConfig,
}
