is there anything wrong with code like this? ```/** * Update milestone by milestoneId * @param re

/**
 * Update milestone by milestoneId
 * @param request
 * @param env
 * @returns
 */
const updateMilestone = async (request: Request, env: any) => {
    try {
        const params = new URL(request.url).searchParams
        const milestoneId = parseInt(params.get('milestoneId') || '')
        const milestoneData: any = await request.json()
        const fields: string[] = []
        const values: any[] = []
        let index = 1
        for (const [key, value] of Object.entries(milestoneData)) {
            if (value !== undefined) {
                fields.push(`${key} = ?${index}`)
                values.push(value)
                index++
            }
        }
        if (fields.length === 0) {
            return new Response(JSON.stringify({ error: 'No fields to update' }), { status: 400 })
        }
        values.push(milestoneId)
        const query = `UPDATE milestone SET ${fields.join(', ')}, updatedAt = CURRENT_TIMESTAMP WHERE _id = ?${index}`
        const { success } = await env.DB.prepare(query)
            .bind(...values)
            .run()
        return new Response(JSON.stringify({ success }), { status: 200 })
    } catch (err: any) {
        return new Response(JSON.stringify(err), { status: 500 })
    }
}
