    entry: v.array(
      v.object({
        id: v.string(),
        changes: v.array(
          v.object({
            field: v.string(),
            value: v.object({
              messaging_product: v.string(),
              metadata: v.object({
                phone_number_id: v.string(),
                display_phone_number: v.string(),
              }),
              contacts: v.array(

                    name: v.string(),
                  }),
                  wa_id: v.string(),
                })
              ),
              messages: v.array(
                v.union(
                  v.object({
                    from: v.string(),
                    id: v.string(),
                    timestamp: v.string(),
                    type: v.literal("text"),
                    text: v.object({
                      body: v.string(),
                      preview_url: v.optional(v.boolean()),

                  v.object({

                      sha256: v.string(),

                    }),
                  })
..
  },
  handler: async (ctx, args) => {
..
    const type = value.messages[0].type;

    if (type === "text") {
      await ctx.runAction(internal.datatypes.text.run, args);
    } ...
    await ctx.runMutation(internal.data.insert, args);
  },
