Uncaught ReferenceError: Buffer is not defined

Hello I'm getting the following error:

✘ [ERROR] service core:user:industries: Uncaught ReferenceError: Buffer is not defined

    at null.<anonymous> (index.js:3223:11

✘ [ERROR] service core:user:industries: Uncaught ReferenceError: Buffer is not defined

    at null.<anonymous> (index.js:3223:11

I have added compatibility_flags = [ "nodejs_compat" ] and am importing node:buffer.

import { Hono } from 'hono'
import { Buffer } from 'node:buffer';
globalThis.Buffer = Buffer; //✘ [ERROR] service core:user:industries: Uncaught ReferenceError: Buffer is not defined
const { Index, Document, Worker } = require("flexsearch");
import { parse } from 'csv-parse/sync'

import { Hono } from 'hono'
import { Buffer } from 'node:buffer';
globalThis.Buffer = Buffer; //✘ [ERROR] service core:user:industries: Uncaught ReferenceError: Buffer is not defined
const { Index, Document, Worker } = require("flexsearch");
import { parse } from 'csv-parse/sync'

Does anyone have any other suggestions? Thanks and kind regards
