Hi @madhukar.koratagere,

Welcome to the Auth0 Community!

We are currently seeing an issue where certain file sizes are not importing correctly. A fix is being rolled out early next week. Could you please tell us the size of the file you are importing?

reference: File size limit for Bulk User Imports looks getting lower than 500KB as specified?

Thanks for your reply Dan, i did see the limitation on the file size as being 500KB in the documentation, hence have kept the file size much lower.

I also tried a scenario where import file contains only 1 user and the format of the file is also verified json format.

Edit: removed sensitive info

Hi @madhukar.koratagere,

I removed the code you posted because it contained tokens and other info that could be considered sensitive.

Let’s wait until the bug is resolved and see if you are still returned the error.
