When user is created with API the S3 folder is not created, no error

[cloudlady911]

So I am trying to create a user using the api. This user needs to have a filesystem that connects to S3.

This is my json payload:
I don't get any error and the user is created, but no s3 filesystem is created. What am I doing wrong?
