Flex 500H manual migration of user account configurations

This is already my second consultation regarding migrating the configuration from USG Flex 200 to Flex 500H.
This time, I am trying to migrate part of the configuration related to user account definitions (including passwords).

I have successfully extracted the necessary information from the Flex 200 configuration file and adapted its format to meet the requirements of Flex 500H, while maintaining the required configuration file structure.
However, when I load the modified file and run the configuration test, it fails.

My question is: what could be causing this?
The structure of the configuration file for defining a single user seems obvious:

/ object user-object user "kaktusus"
/ object user-object user "kaktusus" "role" "user"
/ object user-object user "kaktusus" "password" "$$LCcs4rYU$EsaVbjOJ$T5IyhXbLPL3la2Xg3ldsACQqcUVGxC08AnLLS2h2BDSMwsXfJxd5hCs1Tm45B8aQl1/mQxSNjCt73p3B4PSObE0l8xb9pdGU6YiNPDT1ufcpAmcbZgun45IwT9ryfb7IM4DBK4SLtjDI7ClP2/mQRQxhnx4FDkvI1TPoHxQzCYw2OAeJgLF84t4iQ11nM9JlXhsmhPavX6mBYU0DwGeQ9e3XmN27vv8J55B1ELUL+NV/Qatudk1JgXJiU6xYXG18FruS9JsRawD6ORzPnRkjXxtel+BMbxsuCL2rn//IkJpplpZ0pHXiYqzLiQAwuYzPpXwG5eZwrXsmGgUh2eRMo/BLGycKt401zGKeHapBRdU$"
/ object user-object user "kaktusus" "description" "VPN User"
/ object user-object user "kaktusus" "logon-lease-time" "480"
/ object user-object user "kaktusus" "logon-reauth-time" "480"

My intuition tells me that the problem may occur at the password setting stage …
How can I deal with this problem without having to manually enter the configuration of dozens of users through the GUI❔

After completing the process successfully, I can share the scripts (offline) that I prepared and which are very useful. They also include the conversion of the static DHCP host list. 😎
