onAfterUpload not throwing error in uploader.on('end')

[guillaumemach]

Hi all,

I'm having an issue:

We are trying to perform checks in the settings.onAfterUpload callback (if I understood correctly it is only server side). If one check fails we want to return an error, and catch it in the "end" event (client side).

• If we throw an error in the settings.onAfterUpload callback, everything stops and the "end" event never triggers
• If we return an error in the settings.onAfterUpload callback, the "end" event is triggered but no error is received. And we can't find a way to return an error here.

Is there a way to do this ? Is this a bug ?

Meteor@2.12 ostrio:files@2.3.3

Thanks a lot for your help,

Guillaume

Hello @guillaumemach onAfterUpload is purely async and happens after upload fully recieved on the server. I'd suggest to look for other hooks in order to complete your goals, like onBeforeUpload which can get used on the client as well

Hello @dr-dimitru ,

Thanks for your reply. Which hook would you recommend to perform checks on the uplaoded file ? We tried onUploaded, but same problem nothing returns to the client side events (or maybe we did something wrong).

@guillaumemach for fully uploaded file the only option is onAfterUpload, just don't expect events on the client, I'm suggesting to:

1. Add verified or similar option to meta
2. subscribe on uploaded file for changes in meta.verified
3. Check file in onAfterUpload and update meta.verified
4. Perform action based on changes in meta.verified
