Importing users from SAP Commerce Cloud (pbkdf2-sha1), login fails

I’m trying to export users from SAP Commerce Cloud and import them into auth0.
I have exported the encoded passwords and converted them to base64 encoding with this format for the custom_password_hash:
$pbkdf2-sha1$i=1000,l=64$base64EncodedSalt$base64EncodedPassword

The import is successful but the login fails with:
Verification failed for the provided custom_password_hash

Here is a complete example of my import file:
[
{
“email”: “test@yahoo.com”,
“email_verified”: true,
“given_name”: “Test Me”,
“name” : “Test Me”,
“custom_password_hash”: {
“algorithm”: “pbkdf2”,
“hash”: {
“value”: “$pbkdf2-sha1$i=1000,l=64$MzNiOWYwZDcwOWVhMGMwNDUxYmM2MzRmYjNmMDhjMDM$ZjRhN2NhMzRlY2RkNDRjZDQ4OWE0OTNkNzM0NWU3ZmJjNzUwNzk5YmFkNjM3ZDVlNDhkYzFiNTBhOTQzZTllZTI2ODAyYzJkMmY3MWY2MDJiOTk1YzM2MTk3MmY1MDQ0OTk0ZmJkMzczMTMzNmVjMWQxYjU0ZDg4ZWJmOGQxNGY”,
