Failed to upload file to cloud storage [-0]

[freedomtrain]

I have adding the needed S3 info to settings.json.
When I start sovereign the console info is that "Amazon Web Services for resource storage in cloud... OK"

When I attempt to upload a picture for the users avatar I receive the following error message
"Failed to upload file to cloud storage [-0]"
Is there a way to understand why I'am receiving the error message ?
Have I missed a setting ?

Thanks !

Probably a setting on S3 itself (in my experience it was mostly properly configuring this that was a bit critical). Did you check the documentation of the Slingshot package used for connecting Meteor apps to AWS? Here's the repo: https://github.com/CulturalMe/meteor-slingshot

Can point me to the code that handles the picture validation ?

Thanks !
