const _info = globalThis.console.info
globalThis.console.info = (...args) => {
  _info(...args)
  if (
    args.some(
      (a) => typeof a === 'string' && a.includes('Successfully uploaded source maps to Sentry')

@VityaSchel

@VityaSchel I tried reproducing this (see https://github.com/Lms24/gh-sentry-javascript-17511-sveltekit-build-hangs) but so far wasn't able to reproduce any hangs after source maps were uploaded. I ran this with bun --bun run build as well as with bun run build -- same result. Please let me know what to change in my repro or alternatively provide your own minimal reproduction. Thank you!

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you remove the label Waiting for: Community, I will leave it alone ... forever!

@CaptainAchilles

@CaptainAchilles did you also upgrade any SDKs of Sentry or did you only update your Next version. It would be interesting to know if any updates fixed it and/or if just Turbopack doesn't have this issue (since this is the default now in Next16)

Nah just upgraded straight to the next16 and nothing else.

The build time is also significantly faster (7m -> 2m). I was initially skeptical that source maps were being skipped entirely but I could clearly see them being uploaded in the logs.
