Reference error process is not defined when using in coudflare pages

[yalamber]

I am using this on cloudflare pages, When I try to use KV I receive below error.
"ReferenceError: process is not defined"
My CFKV class is as below

import { binding } from 'cf-bindings-proxy';
import type { KVNamespace, KVNamespaceListResult } from '@cloudflare/workers-types';

type KVGetOptions = 'text' | 'json' | 'arrayBuffer' | 'stream';

export default class CFKV {
	namespaceBinding: KVNamespace;
	constructor(namespace: string) {
		this.namespaceBinding = binding<KVNamespace>(namespace);
	}

	get<T = 'text'>(KEY: string, type: KVGetOptions = 'text'): Promise<T | null> {
		switch (type) {
			case 'json':
				return this.namespaceBinding.get<T>(KEY, 'json');
			case 'text':
				return this.namespaceBinding.get(KEY, 'text') as Promise<T | null>;
			case 'arrayBuffer':
				return this.namespaceBinding.get(KEY, 'arrayBuffer') as Promise<T | null>;
			case 'stream':
				return this.namespaceBinding.get(KEY, 'stream') as Promise<T | null>;
			default:
				return this.namespaceBinding.get(KEY, 'text') as Promise<T | null>;
		}
	}

	set(KEY: string, value: string, { ttl }: { ttl: number }) {
		return this.namespaceBinding.put(KEY, value, {
			expirationTtl: ttl
		});
	}
	remove(KEY: string) {
		return this.namespaceBinding.delete(KEY);
	}

	async removeAllWithPrefix(prefix: string) {
		let cursor: string | undefined = undefined;
		do {
			try {
				const result = await this.list(prefix, 1000, cursor);
				if (!result.list_complete && result.cursor) {
					cursor = result.cursor;
				} else {
					cursor = undefined;
				}
				// Remove each key
				for (const key of result.keys) {
					await this.remove(key.name);
				}
			} catch (error) {
				console.error('Error removing keys with prefix:', error);
				throw error;
			}
		} while (cursor !== undefined);
	}

	list(
		prefix: string,
		limit: number = 1000,
		cursor: string | undefined = undefined
	): Promise<KVNamespaceListResult<unknown, string>> {
		return this.namespaceBinding.list({
			prefix,
			limit,
			cursor
		});
	}
}
