Remix source-map-support `TypeError: Column must be greater than or equal to 0, got -1`

Using bun and express to run remix, I am running into an error with source-map-support.

With code in express like

sourceMapSupport.install({
  retrieveSourceMap: function (source) {
    console.log(source, `${source}.map`)
    return {
      url: source,
      map: fs.readFileSync(`${source}.map`, "utf8"),
    }
  },
})

to restore sourcemaps, I get the error:

(omitting the retrieveSourceMap option results in the same error)

I can confirm that the files exist at that location. My remix.config.js looks like:

/** @type {import('@remix-run/dev').AppConfig} */
export default {
  ignoredRouteFiles: ["**/.*"],
  serverModuleFormat: "esm",
  appDirectory: "src/remix",
};

I pull remix into bun like:

import * as build from "../build/index.js"

app.all("*", createRequestHandler({ build: build as any }))

and have the dev command: "remix dev --manual -c \"bun --watch run src/index.ts\""

The sources I get if I log (based on below comment):

Solution

  • Error.captureStackTrace(this, this.constructor) breaks when used in custom errors, otherwise all that is needed is:

    import sourceMapSupport from "source-map-support"
sourceMapSupport.install()
