Hi @marcel3,

Thanks for reaching out to the Auth0 Community!

I understand that you are encountering problems with Bulk User Import.

Having looked closely at your JSON file, I noticed some values that are not following the [Bulk User Import Database Schema](https://auth0.com/docs/users/import-and-export-users/bulk-user-import-database-schema-and-examples).

First, could you please make sure that your `hash.encoding` values are either `base64` or `hex` when using `"algorithm"="sha512"` as stated [here](https://auth0.com/docs/users/import-and-export-users/bulk-user-import-database-schema-and-examples#md-or-sha).

Please let me know if this addresses the issue.

Thank you.
