Salesforce provisions errors

Hi,
I am trying to integrate salesforce application with OKTA for provisioning users from OKTA to Salesforce.

I Have successfully configured the API integration and checked the Create ,Update and deactivate.

The flow goes like this:
A user is created in AD and assigned to the relevant Securiy Group (For instance : Salesforce_managers).
Then I import the user from AD to OKTA.
Then I assigned the Salesforce_manager group to salesforce application in order the user to be created in salesforce.(Provision)

However, when I try to assign a user to the salesforce application in order the user to be created in salesforce I get an error:
“Automatic provisioning for user test has failed. User test is not a valid value for the type xsd:dateTime.”

I tried to look for this attribute on the OKTA profile and also on the Salesforce profile and did not find it.

What am I missing?
Thanks!
