Could not determine debug ID when using stdin with esbuild

[TheHolyWaffle]

Environment

@sentry/esbuild-plugin version 3.2.1
esbuild version 0.25.0

Related to an earlier attempt to fix this by someone: #522

Steps to Reproduce

1. Create a build.js file with the following content:

import { sentryEsbuildPlugin } from '@sentry/esbuild-plugin';
import esbuild from 'esbuild';
import { join } from 'node:path';

const result = await esbuild.build({
        stdin: {
            contents: `export const foo = 'bar';`,
        },
        outfile: join(options.outDir, `${options.outputFile}.js`),
        bundle: true,
        platform: 'node',
        target: `node${nodeVersion}`,
        external: ['@aws-sdk/*', 'dd-trace', 'datadog-lambda-js'],
        treeShaking: true,
        sourcemap: true,
        minify: true,
        plugins: [
            sentryEsbuildPlugin({
                org: 'REDACTED',
                authToken: 'REDACTED',

                project: options.sentry?.project ||,

                release: {
                    name: options.sentry?.release,
                    dist: options.sentry?.dist,
                    setCommits: { auto: true, ignoreMissing: true },
                },
                debug: true,
            }),
        ],
    });

Expected Result

It should generate sourcemaps for the provided stdin content and upload them to Sentry. Replacing the stdin option with an entryPoints: ['path/to/file.js'], does result in sourcemaps being generated and uploaded to Sentry.

Actual Result

Logs:

No sourcemaps are uploaded

Hey @TheHolyWaffle (nice username btw), thanks for reaching out!

This is currently not supported and unfortunately I doubt this will be highly prioritised atm. Could you try to solve your use case with just Sentry CLI instead?

[TheHolyWaffle]

I can workaround this by writing the content to a temporary file. And using that temporary file as the entrypoint for esbuild. It achieves the same but with the extra steps of writing to a file.
