Remix integration issue

I integrated the postgres npm in my Remix project and used the sample code given on the Remix guide page. Everything is same as instructed on the guide but I get an error when I run the project:
[server] TypeError: Unsupported scheme "cloudflare" for module "cloudflare:sockets". Supported schemes: [
"data",
"blob",
"file",
"http",
"https",
]
