Whats wrong with my wrangler.toml file?

For some reason my D1 database isnt showing up. It does exist but the page function doesnt seem to know about it despite my wrangler.toml file defining it. wrangler.toml

name = "my_app"
compatibility_date = "2023-10-30"
pages_build_output_dir = "./dist"

[[d1_databases]]
binding = "DB"
database_name = "my_app_database"
database_id = "(guid)"
migrations_dir = "sql/migrations"

[vars]
STAGE = "local"

[env.preview.vars]
STAGE = "preview"

[env.production.vars]
STAGE = "production"

name = "my_app"
compatibility_date = "2023-10-30"
pages_build_output_dir = "./dist"

[[d1_databases]]
binding = "DB"
database_name = "my_app_database"
database_id = "(guid)"
migrations_dir = "sql/migrations"

[vars]
STAGE = "local"

[env.preview.vars]
STAGE = "preview"

[env.production.vars]
STAGE = "production"

Function code

import { D1Database } from "@cloudflare/workers-types";
import EventContext from "./EventContext";

class Database {
  db: D1Database;

  constructor(ctx: EventContext) {
    if (!ctx.env.DB) {
      console.error("Context environment:", ctx.env);
      throw new Error("Database instance is not available in the environment context.");
    }
    this.db = ctx.env.DB;
  }
...

import { D1Database } from "@cloudflare/workers-types";
import EventContext from "./EventContext";

class Database {
  db: D1Database;

  constructor(ctx: EventContext) {
    if (!ctx.env.DB) {
      console.error("Context environment:", ctx.env);
      throw new Error("Database instance is not available in the environment context.");
    }
    this.db = ctx.env.DB;
  }
...

I would try updating your compatibility date to a more recent one. My D1 has been working with a date of 2024-05-02

I'll give that a shot. ty

Well, I did that and it's still not working. Page Functions settings:

Here's my wrangler.toml again

name = "(app name)"
compatibility_date = "2024-05-02"
pages_build_output_dir = "./dist"

[[d1_databases]]
binding = "DB"
database_name = "(database name)"
database_id = "(D1 database ID)"
migrations_dir = "sql/migrations"

[vars]
STAGE = "local"

[env.preview.vars]
STAGE = "preview"

[env.production.vars]
STAGE = "production"

name = "(app name)"
compatibility_date = "2024-05-02"
pages_build_output_dir = "./dist"

[[d1_databases]]
binding = "DB"
database_name = "(database name)"
database_id = "(D1 database ID)"
migrations_dir = "sql/migrations"

[vars]
STAGE = "local"

[env.preview.vars]
STAGE = "preview"

[env.production.vars]
STAGE = "production"
