Unable to Publish UEFN Project – “Marketplace Discovery Failed”

[chief_mayv]

Summary

Hello,

I am currently unable to publish my UEFN project. Every time I try to create or publish a private/public version, the publishing process fails with the following error:

“Module bcece409-4fe9-b698-786e-c9b18411e2ef in candidate link 7761-0456-8294?v=1: Cannot publish project b8b79f0a-4afa-a7f1-9c62-a9a1c0c89de9. Module bcece409-4fe9-b698-786e-c9b18411e2ef Marketplace discovery failed. Please re-upload the module or contact support if the issue persists.

publishing_with_product_discovery_failed”

I have already tried reopening UEFN, restarting the session, launching another memory calculation and uploading a new private version, but the issue still persists.

EDIT :
Additional information:

I completely removed all Marketplace, entitlement, offer, bundle and in-island transaction code from the project. I rebuilt the Verse code, launched a new session, completed another memory calculation and attempted to upload a new private version.

The project still fails with the exact same module ID and the same error:

“Module bcece409-4fe9-b698-786e-c9b18411e2ef Marketplace discovery failed.”

The Entitlement Catalog is now empty, so this appears to be a stale or corrupted Marketplace association on the project/module backend rather than an active entitlement remaining in the project.

Could the affected module or Marketplace discovery data please be reset or reprocessed server-side?

I’m having a similar issue. I published my map yesterday unlisted, and today I was going to publish it publicly with some updates (did not touch entitlements) and I’m getting this error:

My island code is 7153-0554-8480

Getting a similar issue and I think it’s related.

Mine is a TWDU island so it can’t even have entitlements, yet I get this error when trying to publish.

I have now created around 20 different private codes, I completely disabled localization, deleted props, etc, nothing helps, so I can’t publish a new update to my game.

i am having the same problem here, i reverted to a previous snapshot and it worked with the same entitlements and offers nothing changed, but the latest one dont. this happens after i upload a private version. i think this start to happen only after the update.

Hi having the same issue

The issue is caused by world UI widgets.

I added a few after the latest update and wasn’t able to publish any of the 20+ island codes i created. Remived world widgets and it no longer gave me this error, I just published without issues.

Needs to be checked, creators have been waiting forever for world UI.

Can confirm, I remove all In-World UI Widgets, and it fixed it.
Seriously, how is it even happening and why reason is “Marketplace Discovery Failed” for this??

I also can confirm Im unable to publish after I put in-world UI in an island
