Import user failed - error with zero details from extension

[mab]

I tried importing the user by extension. Simple case. But I have got an error with zero details
"Unable to import user “test.test@test.com”: " . What could be wrong here?

[
    {
    	"user_id": "15580",
        "email": "test.test@test.com",
        "name" : "test.test@test.com",
        "custom_password_hash": {
            "algorithm": "md4",
            "hash": {
                "value": "db346d691d7acc4dc2625db19f9e3f52"
            }
        }
    }
]

Hi @mab ,

This error could be caused by the incorrect hash value and the missing encoding. I did the following test and it works. Here are the detials.

1. go to https://www.md5hashgenerator.com/, generate the hash for string “password”
2. in the extension, import the JSON file with below scripts.

[
    {
        "email": "test.test@test.com",
        "name" : "test.test@test.com",
        "custom_password_hash": {
            "algorithm": "md5",
            "hash": {
                "value": "5f4dcc3b5aa765d61d8327deb882cf99",
                "encoding": "hex"
            }
        }
    },
    {
        "email": "test2.test2@test.com",
        "name" : "test2.test2@test.com",
        "custom_password_hash": {
            "algorithm": "md5",
            "hash": {
                "value": "5f4dcc3b5aa765d61d8327deb882cf99",
                "encoding": "hex"
            }
        }
    }
]

Could you please try my scripts and confirm how it goes? Thanks!
