],
"detail": "Error in adding the user: testoviy22@mail.ru to the user store.",
"status": "500"

Solution

Seems you are using an LDAP server as your primary userstore, and that server doesn't support the attribute named "comment" Refer to the note in https://is.docs.wso2.com/en/latest/references/extend/provisioning/extend-scim2-user-schemas/#map-the-custom-claim

You can use the word "customClaim" (or any other preferred word) as the Mapped Attribute only when using a JDBC userstore because JDBC userstores will automatically create a new attribute if it does not already exist in the user store. However, If you are using LDAP or Active Directory, you will have to use an attribute that exists in the user store already.

Change the mapped attribute of the local claim to some valid attribute in the LDAP schema
