event/item_before_load returning 404

rekkyrosso — Fri, 28 Feb 2025 16:08:59 GMT

I have a web app (ampcast.app) with extended quota.

When I start playback I see this error in the console:

POST https://cpapi.spotify.com/v1/client/.../event/item_before_load 404 (Not Found)

Uncaught (in promise) CloudPlaybackClientError: PlayLoad event failed with status 404

This is affecting the playback state of my app which now doesn't seem to get updated properly.

This happens for every track. Tested in Chrome and Firefox.

Is anyone else experiencing this?

Any update on this issue? I came across the same error when transferring playback to my web player. Although I get that error, I am able to play music on the web player. There are no other active threads on this, or resources to debug it.

Also experiencing this issue when transferring playback. However, I am able to play music via the web player, I believe it has to be an issue with the spotify API making a call to the internal spotify endpoint you mentioned.

Same issue here. Seems to be caused by the Web Playback SDK itself not properly handling a promise - the network events are coming in properly, playback is continuing, but the events are not being distributed.

A follow-up to my initial bug report.

A result of this 404 error is that the `loading` state of the player is not updated.

It seems like this endpoint (event/item_before_load) is for reporting only? But I'm just guessing.

The Spotify Player SDK should catch this error and update the internal `loading` state regardless of the error. So please don't just fix your servers. The SDK also needs fixing.

Can we get an answer to this please?

Is it common for questions to go unanswered like this? Is there another place to submit bug reports that I should be using instead?

Could someone take a look at this???

Also seeing this error in my web app. This prevents the player from actually playing the requested track and breaks the app.

Edit: The playback problems don't seem to be directly related to this error so I'll take my previous message back. However: This is still very annoying and leads to a lot of verbose output in the console. Please add a catch to the failing Promise and handle it gracefully.

Thank you!

Let me add my voice to this request too.

I successfully connect to the Spotify Web Playback SDK, and the music plays, but I get the following console error (Mac/Chrome v136) when hitting play:

index.js:18
POST https://cpapi.spotify.com/v1/client/redacted/event/item_before_load 404 (Not Found)

index.js:33
Uncaught (in promise) CloudPlaybackClientError: PlayLoad event failed with status 404

Seems like it's been fixed now.
