Unable to deploy express.js project: EADDRINUSE: address already in use

Hello, I was trying to deploy a new service consisting of a express.js server and was having trouble getting it to deploy. I have another service that is also using express that is working perfectly fine, and I have this one setup in the exact same way (using the PORT env to listen on) but this one seems to have trouble listening on any given port. I have also tried specifying 0.0.0.0 with no luck. Thanks in advance! Error log:

Now listening at http://localhost:8059!
node:internal/errors:496
ErrorCaptureStackTrace(err);

Express server code:

const port = process.env.PORT || 3000;

import express from 'express';
import { handler as ssrHandler } from './dist/server/entry.mjs';

const app = express();
app.use(express.static('dist/client/'));
app.use((req, res, next) => {
    ssrHandler(req, res, next, locals);
});

app.listen(port, () => {
    console.log(`Now listening at http://localhost:${port}!`)
})

const port = process.env.PORT || 3000;

import express from 'express';
import { handler as ssrHandler } from './dist/server/entry.mjs';

const app = express();
app.use(express.static('dist/client/'));
app.use((req, res, next) => {
    ssrHandler(req, res, next, locals);
});

app.listen(port, () => {
    console.log(`Now listening at http://localhost:${port}!`)
})
